A hot white star in the central regions of the constellation Virgo, close to the Celestial Equator. Like the Sun, Heze is a main sequence star, but is considerably more massive, and also much younger (it formed only about 500,000 years ago, making it about a tenth of the Sun's age). Heze is some 75 light years from the Solar System, in a direction roughly 'upward' through the Galactic disc. Heze has a recently discovered companion star; this is much fainter than the white primary, and is thought to be a dim red dwarf.
