HD 32453 (HR 1631) is a solitary star located in the southern constellation Caelum. With an apparent magnitude of 6.01,[1] it's barely visible to the naked eye under ideal conditions. This star is located 407 light years away based on its parallax shift, but is drifting away at a rate of 5.73 km/s.[2]
HD 32453 has a classification of G8 III,[3] which states it is an evolved G-type star that exhausted hydrogen at its core and left the main sequence. At present it has 2.40[4] times the Sun's mass, but at an age of 700 million years,[4] HD 32453 has expanded to 10[5] times the latter's girth (radius detected from an angular diameter of 0.748 mas[6]). It radiates at 50[7] solar luminosities from its enlarged photosphere at an effective temperature of 5,032 K,[7] which gives it a yellow hue. HD 32453 is slightly metal deficient,[8] and spins slowly with a projected rotational velocity of 2 km/s,[9] common for a giant star.
