}}{{Starbox end}}Tau Andromedae (τ And, τ Andromedae) is the Bayer designation for a star in the northern constellation of Andromeda. It has an apparent visual magnitude of +4.94,[3] which is bright enough to be viewed from dark suburban skies. From parallax measurements made during the Hipparcos mission, the distance to this star can be estimated as roughly {{Convert|710|ly|pc|abbr=off|lk=on}} from Earth. The brightness of this star is diminished by 0.24 in magnitude due to extinction caused by intervening gas and dust.[4]The spectrum of this star matches a stellar classification of B5 III,[4] with the luminosity class of III indicating that this is a giant star. It is radiating about 851 times the luminosity of the Sun.[11]
Naming
In Chinese, {{lang|zh|天大將軍}} ({{lang|zh-Latn|Tiān Dà Jiāng Jūn}}), meaning Heaven's Great General, refers to an asterism consisting of τ Andromedae, γ Andromedae, φ Persei, 51 Andromedae, 49 Andromedae, χ Andromedae, υ Andromedae, 56 Andromedae, β Trianguli, γ Trianguli and δ Trianguli. Consequently, τ Andromedae itself is known as {{lang|zh|天大將軍七}} ({{lang|zh-Latn|Tiān Dà Jiāng Jūn qī}}, {{lang-en|the Seventh Star of Heaven's Great General}}.).[1]
