54 Cassiopeiae
54 Cassiopeiae is a star in the northern constellation Cassiopeia. Located 88 ly (27 pc) from Earth, it has an apparent magnitude of 6.59, which makes it hard to be seen by the naked eye even from dark skies. Its absolute magnitude is 4.4. It is a F-type main-sequence star with a stellar classification F8V, currently fusing atoms of hydrogen into helium at its core.
Astrometric measurements by the Gaia spacecraft suggested the presence of a planetary companion to 54 Cassiopeiae, seven times more massive than Jupiter and with an orbital period of 401 days (1.10 years). This was later rejected by the Gaia team as a false positive caused by a software error. Radial velocity observations also show no evidence for this planet.
