List of stars in Pisces

View on Grokipedia
from Grokipedia
The list of stars in Pisces comprises the cataloged stellar objects lying within the defined boundaries of the Pisces constellation, a zodiacal constellation in the that ranks as the 14th largest among the 88 modern constellations, covering an area of 889 square degrees. Pisces is visible to observers at latitudes between +90° and -65°, best visible in the evening sky during autumn from northern latitudes, and it includes the location of the vernal equinox point where the intersects the . The constellation hosts a diverse array of stars, from naked-eye visible giants to faint white dwarfs, with approximately 18 stars known to possess exoplanets as of the latest catalogs, making it a key area for stellar and exoplanetary studies. Among the most prominent stars in Pisces, ordered by apparent magnitude, is Eta Piscium (Alpherg), the brightest at magnitude 3.62, a G7 IIIa yellow giant located 350 light-years away and part of a . Following it is Gamma Piscium, a G9 III yellow giant with magnitude 3.70 at 138 light-years, notable for its role in the asterism formed by Pisces' western stars. Alpha Piscium (Alrescha), at magnitude 3.82 and 139 light-years distant, is an A0p system whose components are separated by 1.8 arcseconds, representing a key visual marker in the constellation. Other significant bright stars include Omega Piscium (magnitude 4.04, F4IV , 106 light-years), Iota Piscium (magnitude 4.13, F7 V dwarf, 45 light-years), and Beta Piscium (Fumalsamakah) (magnitude 4.53, B6Ve main-sequence star, 492 light-years), the latter being a blue-white emitter near the . Beyond these, Pisces features variable and multiple star systems, such as the suspected variable Epsilon Piscium (magnitude 4.28, K0 III orange giant, 182 light-years) and the binary Delta Piscium (magnitude 4.43, K5 III orange giant, 305 light-years). The constellation also contains fainter but scientifically important objects, including Van Maanen's Star (Van Maanen 2), a DZ8 white dwarf with magnitude 12.4, situated just 14.1 light-years from the Sun and ranking as the third-closest white dwarf after those in Sirius and Procyon systems. Double stars like Zeta Piscium (magnitudes 5.2 and 6.3) and Psi¹ Piscium (magnitudes 5.3 and 5.4) are observable with small telescopes, adding to the constellation's appeal for amateur astronomers. Comprehensive lists of Pisces stars, such as those compiled in astronomical catalogs, typically enumerate hundreds of objects brighter than 10th magnitude, prioritizing Bayer and Flamsteed designations for identification and study.

Constellation Context

Position and Visibility

The constellation Pisces spans a range from 22h 50m to 02h 10m and a range from +34° to -05°, encompassing an area of 889 square degrees and ranking as the 14th largest among modern constellations. This V-shaped pattern straddles the , with its western portion extending into the fourth quadrant of the northern sky and its eastern part crossing into the first quadrant, allowing visibility from a wide range of latitudes between +90° and -65°. Pisces is best observed during northern autumn evenings from to , when it reaches its highest point in the sky after sunset, culminating around midnight in late and early . For observers at latitudes above approximately 33°N, significant portions of the constellation remain visible throughout the night during this period, though the entire figure is not due to its southern extent; southern observers may see it low on the northern horizon in spring evenings. Faint stars within Pisces, many below fourth magnitude, are particularly challenging to observe in urban areas affected by , which can obscure details and require dark-sky sites for effective viewing with or small telescopes. Pisces borders the constellations Aquarius to the south, Pegasus to the southwest, Andromeda and Triangulum to the north, Aries to the east, and Cetus to the southeast, forming a transitional zone in the zodiacal band. Notably, the vernal equinox point—the position of the Sun at the —lies within Pisces' boundaries, a result of that has shifted it from Aries over millennia and will eventually move it into Aquarius around the year 2600.

Historical and Mythological Background

Pisces is one of the 48 ancient constellations cataloged by the Greco-Roman astronomer Claudius Ptolemy in his 2nd-century work , where it is depicted as two fish connected by a cord, representing the forms taken by the goddess and her son Eros to escape the monstrous giant during a mythological conflict on . In this Greek legend, as ravaged the earth, and Eros hid among river reeds but, startled by the monster's approach, leaped into the and transformed into fish; a cord linking their tails ensured they remained together, later placed in the sky by the gods as the constellation Pisces. The constellation held varied significance across ancient cultures, reflecting diverse interpretations of its stellar patterns. In Babylonian astronomy, the region of Pisces was known as "The Tails" (zibbātu or zibbāt sinūnūtu), associated with the tails of a swallow and a fish, and used in omen texts to predict agricultural prosperity, such as river flooding or harvest yields. Arabic astronomers in the medieval period contributed enduring names to its stars, including Alrescha for Alpha Piscium, derived from al-rišā' meaning "the cord" or "the rope," symbolizing the knot binding the two fish. In Hindu tradition, the Revati nakshatra encompasses stars in Pisces, with Zeta Piscium as its prominent luminary, linked to themes of nourishment, prosperity, and transcendence under Mercury's rulership. Chinese astronomy divided the area into multiple asterisms spanning four lunar mansions within the Azure Dragon of the East quadrant, such as Yòugèng ("Livestock Manager"), formed by five stars including Eta Piscium. The naming of stars in Pisces evolved significantly through Arabic scholarly influence during the (8th–14th centuries), when astronomers like Al-Sufi translated and expanded Ptolemaic catalogs, preserving and Arabicizing names that later transmitted to via medieval manuscripts and astrolabes. This legacy culminated in modern standardization, with the approving nine proper names for Pisces stars in 2016, including Alpherg (, from al-fargh "the empty part") and Fum al Samakah (Beta Piscium, meaning "mouth of the ").

Catalog of Notable Stars

Bayer-Designated Principal Stars

The Bayer-designated principal stars in Pisces, assigned Greek letters from alpha (α) to omega (ω) by in his 1603 Uranometria atlas, represent the core visible framework of this zodiacal constellation. These 24 stars are generally faint, reflecting Pisces's lack of highly luminous members, and span a range of evolutionary stages, predominantly evolved giants. Observational data for these stars derive from modern astrometric catalogs, revealing their positions, brightness, and motions relative to the Sun. The table below catalogs the principal Bayer-designated stars, including common names (where IAU-approved), apparent visual magnitude (V), spectral type, distance in light-years (ly), and total proper motion in arcseconds per year (″/yr). Data are compiled for the brighter members (V < 5.0) to highlight representative properties; fainter ones follow similar patterns but with sparser measurements. Values are based on updated parallax and spectroscopic data as of 2023.

Pisces exhibits overall faintness among constellations, with no star exceeding magnitude 3.6 in brightness, limiting naked-eye visibility in urban areas. Distances for these stars typically range from 45 to 492 ly, placing most within the solar neighborhood, while spectral classifications are dominated by G and giants, indicative of post-main-sequence . Proper motions are modest, generally under 0.8 ″/yr, consistent with their proximity. Some stars, such as Alrescha and Alpherg, bear traditional proper names rooted in astronomy, as explored further in the section on stars with proper names. To locate these stars, observers can start from the Great Square asterism in —using its eastern side (from γ Peg to α Peg)—and trace eastward to Aries' bright α Ari (, mag 2.0), where the Pisces circlet and western chain connect the two constellations; η Psc marks the southeastern tip of the western fish. Best visibility occurs in autumn evenings from northern latitudes.

Stars with Proper Names

The (IAU) has approved nine proper names for stars in the constellation Pisces, drawing from diverse cultural and historical traditions to standardize nomenclature in modern astronomy. These names, formalized through the IAU's on Star Names (WGSN), coexist with Bayer designations like α Psc or η Psc, providing a bridge between ancient lore and contemporary scientific usage; for instance, professional catalogs and publications often reference both to ensure clarity. Many of these names trace their origins to astronomy, reflecting the influence of medieval Islamic scholars who cataloged stars with descriptive terms tied to the fishes' imagery in Pisces. Alrescha, applied to α Piscium, derives from the al-rišā meaning "the cord" or "the ," symbolizing the mythical binding the two together in Greco-Roman lore; historical variants include Okda, also for "." Similarly, Fumalsamakah for β Piscium comes from fum al-samakah, translating to "mouth of the ," evoking the constellation's piscine motif as documented in texts. Alpherg, assigned to η Piscium, stems from the al-fargh al-thānī, "the second pouring" or "the pourer," alluding to flow, while an older Babylonian designation for the same star, Kullat Nunu, combines kullat (cord or ) with nunu (), highlighting ancient Mesopotamian views of the stars as tied to aquatic themes. Other approved names incorporate non-Arabic cultural elements, often from global public naming initiatives. Revati, for ζ Piscium, originates from Hindu astronomy, where it refers to a prominent nakshatra (lunar mansion) associated with the goddess Revatī, a figure in Vedic mythology linked to prosperity and marital harmony; this name was ratified by the IAU in 2017 to honor indigenous traditions. Torcularis Septentrionalis, for ο Piscium, is a Latinized form from the 16th-century Almagest translation, meaning "northern wine press" and derived from the Greek lēnos (wine press or trough), possibly metaphorically connecting to the constellation's watery essence in Ptolemaic catalogs. The remaining names emerged from the IAU's 2015 NameExoWorlds contest, celebrating planetary discoveries and cultural heritage. Bélénos, for HD 8574, was proposed by and honors the Celtic god of light and healing, , reflecting mythology's ties to solar and restorative forces. Citadelle, assigned to HD 1502, draws from the historic fortress in , , symbolizing resilience and ancient Near Eastern architecture as part of a Syrian initiative. , for HD 218566, commemorates the Bronze Age kingdom of in modern , one of the earliest urban civilizations, underscoring archaeological significance in Semitic history. Parumleo, for WASP-32, is Latin for "little lion," selected by to evoke the symbol and the nation's independence struggles, blending Western linguistic roots with Southeast Asian identity. These contest-derived names, approved between 2015 and 2019, promote worldwide participation in astronomy while preserving .

Categories of Interesting Stars

Variable Stars

The variable stars in Pisces are predominantly late-type giants and supergiants that display pulsational variability, reflecting the constellation's abundance of evolved (AGB) stars. These include , semiregular variables, and irregular variables, with brightness changes arising from radial pulsations in their extended atmospheres. The General Catalogue of Variable Stars (GCVS) catalogs over 100 variable stars within the boundaries of Pisces, of which approximately 20 are brighter than magnitude 12, making them accessible to and observers with moderate equipment. Notable examples include R Psc, a classic Mira-type long-period variable that undergoes dramatic brightness changes from magnitude 7.0 at maximum to 14.8 at minimum over a period of 345 days. This star's large and regular pulsation make it a for studying mass loss and dust formation in AGB stars. Another prominent is T Psc, with a period of 395 days and a magnitude range of 7.6 to 13.1, exhibiting strong molecular bands in its spectrum indicative of oxygen-rich chemistry. Semiregular variables are also common, such as RT Psc, a classified as SRb with a primary period of 516 days and a visual magnitude range of 9.2 to 10.5, showing semi-periodic fluctuations due to multiple pulsation modes. TX Psc, a carbon-rich AGB star classified as Lb (slow irregular), varies between magnitudes 4.8 and 5.2 with evidence for a period around 220 days, though its is complex due to pulsations and circumstellar . L Psc represents a semi-regular example with a magnitude range of 8.2 to 9.0 and irregular periods on the order of 100–200 days, typical of multi-mode pulsators in this class. Irregular variables like UV Psc exhibit small, non-periodic fluctuations in brightness from magnitude 8.3 to 9.0, likely driven by convective activity or low-amplitude pulsations in its evolved envelope. The variability of these stars provides insights into , with in particular serving as distance indicators through the . For oxygen-rich Miras, the absolute visual magnitude can be estimated as Mv=−2.76log⁡P−1.58M_v = -2.76 \log P - 1.58, where PP is the pulsation period in days; this empirical relation, calibrated from observations, links longer periods to higher luminosities and enables distance determinations when combined with apparent magnitudes.

Multiple and Double Stars

Pisces hosts a variety of multiple and systems, predominantly wide visual doubles observable with small telescopes, alongside a smaller number of spectroscopic binaries and eclipsing systems. Approximately 20 such visual pairs are accessible to amateur astronomers, with separations ranging from a few arcseconds to over 30 arcseconds, allowing resolution at magnifications as low as 50× to 200× depending on the pair's tightness. Spectroscopic binaries, detected through variations, are less common in the constellation, while eclipsing binaries represent a minor fraction, often studied for their light curves in professional observations. Multiplicity in these systems influences measurements, as the combined brightness of components must be accounted for when cataloging total visual magnitude, typically yielding a value brighter than the primary alone by 0.1 to 1 magnitude. A prominent example is α Piscium, known as Alrescha, an optical system marking the knot joining the two in the constellation's asterism. The components, separated by 1.8 arcseconds, have visual magnitudes of 4.3 and 5.2, with both classified as peculiar A-type stars: the primary an A2 with enhanced and , and the secondary an Am metallic-line star. Despite the close apparent proximity, the pair is likely unbound, with no detectable orbital motion over observed epochs, rendering any potential period indeterminate. Another notable visual double is 57 Piscium (STF 88), a wide pair with components of magnitudes 5.3 and 5.5 separated by 29.8 arcseconds at a of around 280 degrees. The primary appears orange due to its K-type spectral classification, contrasting with the fainter companion, making it an easy target for low-power telescopes. Orbital parameters remain unknown for this system, consistent with many wide doubles in Pisces that show no measurable relative to each other. For spectroscopic binaries, δ Piscium (magnitude 4.4, K5III giant) features a distant optical companion of magnitude 14 at 135 arcseconds, though the primary itself shows no confirmed close stellar companion via ; however, systems like 58 Piscium exemplify true spectroscopic pairs in the constellation, with an unseen companion orbiting a K0 primary (combined magnitude 5.3) over an undetermined period. Eclipsing binaries are rare but include SU Piscium, an early-type system with minimum component masses around 11 solar masses derived from data.

Stars with Exoplanets

The constellation Pisces hosts numerous confirmed systems, with at least 18 stars known to have as of late 2025, contributing to our understanding of planetary formation around a variety of stellar types from cool red dwarfs to evolved giants. Discoveries in this region have been driven primarily by (RV) surveys using instruments like HARPS and HIRES, which detect the gravitational tug of orbiting , and transit photometry from missions such as Kepler/ and TESS, which observe dips in stellar brightness as pass in front. These methods have revealed a range of planet types, including hot super-Earths, mini-Neptunes, and gas giants with orbits from mere days to decades, spanning 0.02 to over 7 AU. Pisces' relatively nearby stars, many within 100 light-years, facilitate detailed follow-up observations, including atmospheric studies with telescopes like the (JWST). Notable systems illustrate the diversity of exoplanets in Pisces. One of the closest is 54 Piscium, a K0V main-sequence star at 36 light-years with visual magnitude 5.9, hosting a sub-Saturn-mass (54 Piscium b) discovered via RV in 2003; the has a minimum mass of 0.20 masses and an eccentric orbit of 62.3 days at 0.27 AU, notable for its proximity to the star despite the cool host temperature. Another early find is 109 Piscium, a G3V star 108 light-years away and magnitude 5.1, with a long-period (109 Piscium b) detected by RV in 1999; the planet's minimum mass is 6.38 masses on a 2,975-day orbit at 2.16 AU, representing one of the first super-Jupiters identified. Multi-planet systems are also prominent. GJ 9827, an M6V 97 light-years distant and magnitude 10.4, hosts three small (b, c, d) found by K2 transit observations in 2017; these include two super-Earths (1.2-1.9 radii) and a (2.1 radii) on ultra-short periods of 1.2, 3.6, and 6.2 days, respectively, making it a key target for studying close-in rocky worlds' atmospheres—recent JWST data on d revealed a water-vapor-dominated "steam world" envelope. Similarly, HD 4203, a G5V star 250 light-years away and magnitude 8.7, features two gas giants: HD 4203 b (2.23 masses, 432-day at 1.17 AU) detected in 1999 and HD 4203 c (2.17 masses, 18.4-year at 6.95 AU) confirmed in 2014 via RV, highlighting outer dynamics in a Sun-like system. Among the most intriguing is Gliese 12 b, orbiting a cool M3V 40 light-years away with magnitude 12.0; discovered by TESS transit in 2024, this Earth-sized (1.0 ) receives similar stellar flux to , placing it squarely in the for potential liquid water, though its exact atmosphere remains under investigation. Gamma Piscium, a brighter G8III giant at magnitude 3.7 and 138 light-years, hosts a Jupiter-mass (1.34 masses) on a 1.5-year at 1.32 AU, detected by RV in 2021, offering insights into planet retention around evolving stars.
