Pi2 Doradus

Pi2 Doradus, Latinized from π2 Doradus, is a solitary star located in the southern constellation Doradus. It is faintly visible to the naked eye as a yellow-hued point of light with an apparent magnitude of 5.38. The object is located relatively close at a distance of 277 light-years based on Gaia DR3 parallax measurements, but it is receding with a heliocentric radial velocity of approximately $$. At its current distance, Pi2 Doradus' brightness is diminished by 0.27 magnitudes due to interstellar extinction and it has an absolute magnitude of +0.78.

Pi2 Doradus has a stellar classification of G8 III, indicating that it is an evolved G-type giant star. It is a red clump star that is currently on the horizontal branch—fusing helium at its stellar core. It has 1.8 times the mass of the Sun but, at the age of 1.61 billion years, it has expanded to 9.84 times the radius of the Sun. It radiates 51.1 times the luminosity of the Sun from its photosphere at an effective temperature of $$ Pi2 Doradus is metal deficient with an iron abundance of [Fe/H] = −0.26 or roughly 55% of the Sun's. Like many giant stars Pi2 Doradus spins slowly, having a projected rotational velocity lower than $$.
