HD 28454, also known as HR 1418, is a solitary, yellowish-white hued star located in the southern constellation Caelum, the chisel. It has an apparent magnitude of 6.1,[2] making it faintly visible to the naked eye under ideal conditions. This star is located relatively close at a distance of about 107 light years based on parallax measurements of Gaia DR3 but is receding with a heliocentric radial velocity of 15 km/s.[5]
HD 28454 is an ordinary F-type main sequence star with a stellar classification of F5.5 V.[3] It has 1.21 times the mass of the Sun[6] and 1.42 times its radius.[7] It radiates 3.26 times the luminosity of the Sun[1] from its photosphere at an effective temperature of 6,468 K.[9] HD 28454 is estimated to be 1.61 billion years,[6] and spins modestly with a projected rotational velocity of 8 km/s.[11] The star is metal deficient, having an iron abundance 56% that of the Sun's.[10]
