HD 28246 (HR 1404) is a solitary star located in the southern constellation Caelum. It has an apparent magnitude of 6.38,[2] placing it near the max visibility to the unaided eye. The star is located relatively close at a distance of about 122[1] light years but is recceding with a heliocentric radial velocity of 14.9 km/s.[5]
HD 28246 has a stellar classification of F5.5 V,[3] indicating that it is an ordinary F-type main sequence star. At present it has 1.78[7] times the mass of the Sun and shines at 3.07 solar luminosities[8] from its photosphere at an effective temperature of 6,519 K,[7] giving it a yellow-white glow. HD 28246 has an iron abundance 105%[9] that of the Sun, placing it at solar metallicity. At an age of 1.58 billion years,[7] it spins leisurely with a projected rotational velocity of 8 km/s.[9]
