HD 76143, also known as HR 3537, is a high proper motion star in the constellation Volans. It has a radial velocity of 40.54 km/s, and is currently drifting away from the Solar System. With an apparent magnitude of 5.33, it is barely visible to the naked eye.

Properties[]

Characteristics[]

This is a subgiant star, with a mass similar to the Sun, but has ballooned to 3 times the radius of the latter. It has a luminosity of almost 17 times that of the Sun, and a temperature of 6605 K, which gives it a yellowish-white hue.

Companion[]

HD 76143 has a faint 12 magnitude companion separated 36.7'' apart. The companion is actually an unrelated background star.[7]
