The Peekskill meteorite is the object resulting from a well-documented meteorite event that occurred in October, 1992, in Peekskill, New York, United States.[1] Sixteen separate video recordings document the meteorite burning through the Earth's atmosphere, whereupon it struck a parked car in Peekskill.[2] The Peekskill meteorite is an H6 monomict breccia;[3][4] its filigreed texture is the result of the shocking and heating following the impact of two asteroids in outer space.[5] The meteorite is of the stony variety, and approximately 20% of its mass is tiny flakes of nickel-iron.[6] When it struck Earth, the meteorite weighed 12.57 kilograms (27 lb 11 oz) and measured 1 foot (30 cm) in diameter. The Peekskill meteorite is estimated to be 4.4 billion years old.[7]

Descent

[edit]

The meteorite fell on October 9, 1992 – an event witnessed by thousands across the East Coast. Numerous residents of Pittsburgh, Philadelphia, and Washington D.C. described the "huge greenish fireball."[8] The meteorite broke up over Kentucky and passed over West Virginia and Pennsylvania on its north-northeast trajectory before striking a parked 1980 red Chevy Malibu at approximately 7:50 pm EDT. After traveling through space at a cosmic velocity of 14.2 km/s (31,760 mph; 51,120 km/h), the meteorite at impact had slowed to 164 mph (241 ft/s; 264 km/h; 73 m/s)[9]

Video

[edit]

As the meteorite fell on a Friday evening, its descent was captured on video by many high school football fans taping local games. The descent was filmed by 16 different cameras. Only a handful of meteorite falls have been caught on film, and only the 2013 Russian meteor event was captured from more angles and localities. The multiple perspectives provided scientists with the ability to calculate the meteorite's flight path to Earth.[2]

Impact

[edit]

After having been slowed by the Earth's atmosphere, the meteorite was traveling at approximately 164 miles per hour (264 km/h) at impact. The Peekskill meteorite smashed through the trunk of a red 1980 Chevrolet Malibu[10] and narrowly missed the gas tank, finally coming to rest in an impact pit beneath the car. Seventeen-year-old Michelle Knapp,[11] the car's owner, heard the collision from inside her home. She later described the sound as "like a three-car crash". Hurrying outside to investigate the noise, Knapp found her car smashed and the meteorite weighing 12.37 kilograms (27 lb 4.3 oz),[12] still warm and smelling of sulfur, beneath it.[9]

Specimens

[edit]

Knapp retrieved the meteorite, after which it was sold to a consortium of three dealers for $50,000.[9][13] Today, small specimens of the Peekskill meteorite sell for approximately $125 per gram.

Knapp had just purchased the car for $300. Immediately following the extraterrestrial impact, the vehicle was sold to Iris Lang, wife of renowned meteorite collector and dealer Al Lang, for $25,000.[9] Since then, it has been on display in numerous museums throughout the world, including New York City's American Museum of Natural History and France's National Museum of Natural History.[14]

The car, as well as the main mass of the meteorite (which currently weighs 890 grams (1 lb 15 oz)), are now in the Macovich Collection of Meteorites.[15] Additional specimens of the meteorite can be found in Chicago's Field Museum, the National Museum of American History at the Smithsonian, and Griffith Observatory in Los Angeles.[16]

Peekskill meteorite

View on Grokipedia
from Grokipedia
The Peekskill meteorite is an H6 , classified as a monomict , that fell to on October 9, 1992, at 19:50 EDT, impacting the trunk of a parked 1980 owned by Michelle Knapp at 207 Wells Street in , (coordinates: 41°17′N, 73°55′W). The main mass weighs 12.37 kg, with additional fragments totaling about 200 g, for a combined mass of 12.57 kg; the stone features light, centimeter-sized H6 clasts embedded in a darker H6 matrix, and its includes (Fa20) and (Fs17). Upon impact, the meteorite punched a hole through the car's trunk, embedding itself nearly intact and becoming coated in red paint from the vehicle, following a loud boom heard after a bright greenish fireball visible across the eastern U.S. The fall was one of the most thoroughly documented in history, witnessed by thousands of people and captured on at least 16 separate video recordings, many taken by high school football fans filming local games in the path of the event. These videos enabled precise reconstruction of the meteoroid's atmospheric trajectory, which spanned approximately 700 km in a northeasterly direction from West Virginia to New York, as well as determination of its pre-entry orbit—making Peekskill only the fourth recovered meteorite for which such detailed orbital parameters were calculated at the time. The event's visibility and multimedia evidence highlighted the potential for amateur observations to contribute to meteorite science, while the stone's recovery provided insights into ordinary chondrite composition and fragmentation dynamics during atmospheric entry. Samples are held in institutions including the Field Museum (470 g) and private collections, underscoring its value for ongoing research into solar system formation.

Classification and Characteristics

Mineralogy and Petrology

The Peekskill meteorite is classified as an exhibiting a monomict texture, consisting of light, centimeter-sized H6 clasts embedded in a darker H6 matrix. This brecciated structure indicates a history of fragmentation and reassembly on the parent body, likely resulting from impacts that caused shock metamorphism and subsequent . The primary silicate minerals are with a composition of Fa20 and orthopyroxene with Fs17, consistent with equilibrated type 6 ordinary chondrites. Accessory phases include , , and metallic nickel-iron alloys comprising approximately 20% of the volume, dominated by kamacite and grains that show typical Widmanstätten patterns indicative of slow cooling. The Peekskill meteorite shares the general formation timeline of H-chondrites, with accretion shortly after calcium-aluminum-rich inclusions (~4.56 billion years ago) and later metamorphic processing on the parent body. Its cosmic-ray exposure age is approximately 27–32 million years, indicating the duration of its journey as a in space.

Physical Properties

The Peekskill meteorite consists of multiple fragments with a total known weight of 12.57 kg. The largest fragment, recovered immediately after impacting a parked , weighed 12.37 kg and represents the primary specimen. This main mass, now distributed among private collections including pieces of 5.2 kg, 1.2 kg, 1 kg, and 470 g, measures approximately 35 cm in length with an irregular, football-like shape. The exhibits magnetic properties attributable to its approximately 20% nickel-iron content. Externally, the primary fragment features a brown fusion crust formed during atmospheric , displaying regmaglypt texture with thumbprint-like indentations. Upon recovery, the stone emitted a sulfurous odor, likely from volatilized compounds.

The Fall Event

Atmospheric Descent

The Peekskill meteorite entered Earth's atmosphere on October 9, 1992, at approximately 7:50 pm EDT (23:50 UT), with an initial velocity of 14.7 km/s (approximately 53,000 km/h). The meteoroid's trajectory originated over West Virginia, where initial fragmentation began, before proceeding in a northeasterly direction over Pennsylvania, covering a ground path exceeding 700 km and terminating near Peekskill, New York. This path rendered the event visible across much of the eastern United States, from areas near Pittsburgh, Pennsylvania, to Washington, D.C., and beyond. The resulting fireball exhibited a pronounced greenish glow, attributable to the emission spectra of present in the composition during atmospheric . It reached a peak visual magnitude of -13, rendering it significantly brighter than the (which has a magnitude of about -12.6), and maintained luminosity for over 40 seconds. Eyewitness accounts and multiple video recordings captured these characteristics, highlighting the fireball's intense illumination and elongated trail. During descent, the meteoroid underwent extensive fragmentation, with major events occurring between heights of 41.5 km and 36.4 km, producing dozens of visible pieces and finer grains estimated at around 1,000 particles of approximately 1 g each. This breakup, driven by aerodynamic pressures of 1–5 MPa, reduced the velocity progressively through and drag, ultimately allowing surviving fragments to reach below 3 km/s at about 30 km altitude. The process exemplified typical dynamics for stony s of this mass (initially 20–25 metric tons), transitioning from hypersonic entry to subsonic dark flight.

Observations and Recordings

The Peekskill meteorite's atmospheric entry on October 9, 1992, was witnessed by thousands of across five eastern U.S. states—West Virginia, , , New York, and —many of whom described it as a fireball** streaking northeastward with a luminous duration exceeding 40 seconds and reaching a peak brightness of magnitude -13. Eyewitnesses reported accompanying explosive sounds, including a crackling like a lasting about 10 seconds near the end of the visible path, as noted in accounts from locations such as . The event's rarity was amplified by its capture on 16 independent video recordings, primarily obtained by high school students and spectators filming Friday night football games in Pennsylvania communities like Johnstown and Purchase Line. These amateur videos, collected from stations including ; Johnstown and , Pennsylvania; and , provided unprecedented multi-angle documentation of the fireball's flight. Astronomers utilized these videos to model the meteoroid's , determining an initial velocity of 14.7 km/s at a height of 46.4 km and confirming its northeasterly path over approximately 700–800 km. The fragmentation sequence, including multiple flares—such as a prominent one at 36.4 km altitude lasting less than one-third of a second—was precisely timed and analyzed from the footage. This well-documented fall marked the first meteorite event to be extensively captured on video by multiple independent sources, garnering significant media attention and predating more famous instrumented recordings like the 2013 Chelyabinsk event.

Impact and Recovery

Collision Details

On October 9, 1992, at 7:50 p.m. EDT, a fragment of the Peekskill meteorite struck the ground in , at coordinates 41°17′11″N 73°54′59″W. The event occurred moments after the meteoroid's atmospheric fragmentation, with the primary recovered fragment—measuring approximately 23 cm across and weighing 12.4 kg—impacting at a of 164 mph (264 km/h). The fragment collided with the trunk of a 1980 red owned by 18-year-old Michelle Knapp, which was unoccupied and parked in the driveway at 207 Wells Street. The impact created a 23 cm dent in the trunk, penetrating the metal and narrowly missing the gas tank, while also embedding into the gravel driveway beneath. The fragment remained warm to the touch, reaching about 100°C, and emitted a distinct sulfurous reminiscent of rotten eggs upon recovery seconds later. No injuries occurred, as the vehicle was empty at the time, and the immediate area was residential with no reported structural damage beyond the car and driveway. The collision's low terminal speed, a result of extensive atmospheric deceleration and breakup, limited the destructive potential despite the meteoroid's initial entry velocity exceeding 14 km/s.

Fragment Recovery

The primary fragment of the Peekskill meteorite, weighing 12.37 kg, was recovered minutes after the fall by 18-year-old Michelle Knapp, who heard the impact and discovered the stone embedded in the driveway beneath her parked car at 207 Wells Street in Peekskill, New York. Additional smaller fragments, totaling approximately 0.2 kg, were found in nearby areas of New York state following the event. Recovery efforts were swiftly organized, involving local authorities who secured the primary site and meteorite enthusiasts who searched the predicted strewn field within hours and over the following days, leading to the collection of the smaller pieces. The main mass is currently held in the Macovich Collection of Meteorites, while specimens are preserved in institutions including the Smithsonian National Museum of Natural History (approximately 739 g) and the Field Museum of Natural History (470 g).

Scientific and Cultural Impact

Research Findings

Petrographic analysis of the Peekskill meteorite samples confirmed its classification as an H6 , characterized by a highly equilibrated texture with recrystallized chondrules and a monomict structure. This determination was made through detailed examination at institutions such as the , where (Fa20) and (Fs17) compositions aligned with H-group standards. Studies of shock features in the , including prominent melt veins and a filigreed matrix, indicate exposure to intense shock pressures on its parent body, consistent with collisional events among H-chondrite precursors. These observations are consistent with the identification of asteroid as the likely source for H-chondrites, based on spectral matching, with dynamical models supporting origins from main-belt asteroids like Hebe for ordinary chondrites. Oxygen isotope ratios measured in the Peekskill samples, with δ17\delta^{17}O ≈ +3.5‰ and δ18\delta^{18}O ≈ +4.4‰, plot within the distinct field defined for H-chondrites, reinforcing its affiliation with this group and highlighting shared formation history in a common reservoir. Additionally, analysis of the video-recorded contributed key data to models of and atmospheric deceleration, enabling more accurate predictions of mass loss and for similar events.

Legacy and Exhibitions

The primary fragment of the Peekskill was sold by its finder, Michelle Knapp, to a of three meteorite dealers for $50,000 shortly after the 1992 fall. The main mass is held in private collections, with specimens continuing to be traded; for example, in 2012, an 83.68 g piece sold for $16,250 at . Today, small specimens of the Peekskill command a of approximately $100 to $200 per gram due to their and documented . The damaged 1980 Chevrolet Malibu, which bore the scars of the meteorite's impact, was sold for $25,000 to meteorite collector Iris Lang and subsequently toured internationally as an exhibit, including a prominent display at France's Muséum National d'Histoire Naturelle in in 2017. The vehicle, insured for up to $1 million at one point, has since entered a private collection but remains available for special exhibitions. The Peekskill event has left a lasting mark on , inspiring features in documentaries such as "OTD in Space" episodes recounting the fall and its video documentation, as well as mentions in books on history like those chronicling famous falls. In , the incident bolsters local tourism, with commemorations for milestone anniversaries marking the date, such as the 30th in 2022, and sites like the impact location drawing visitors interested in cosmic events. Educationally, the Peekskill meteorite serves as a key example in meteorite awareness programs, highlighted by the American Meteor Society in anniversary retrospectives and public outreach to illustrate the reality of meteorite falls and encourage reporting of fireballs.
