HD 63454, formally named Ceibo, is a star located in the southern circumpolar constellation Chamaeleon near the border with Mensa. To see the star, one needs a small telescope because it has an apparent magnitude of 9.36,[2] which is below the limit for naked eye visibility. The object is located relatively close at a distance of 123 light years based on Gaia DR3 parallax measurements[1] but is receding with a heliocentric radial velocity of 33.8 km/s.[5] At its current distance, HD 63454's brightness is diminished by two tenths of a magnitude due to interstellar dust.[13] It has an absolute magnitude of +6.68.[6]
