}}{{Starbox end}}Nu Andromedae (Nu And, ν Andromedae, ν And) is a binary star in the constellation Andromeda. The system has an apparent visual magnitude of 4.5,[3] which is bright enough to be seen with the naked eye. It is approximately {{Convert|620|ly|pc|abbr=off|lk=on}} from Earth.[ Situated just over a degree to the west of this star is the Andromeda Galaxy.[26]]Nu Andromedae is spectroscopic binary[4] system with a nearly circular orbit that has a period of 4.2828 days.[6] The primary component is a B-type main sequence star with a stellar classification of B5 V.[4] The fainter secondary has a classification of F8 V,[6] which makes it an F-type main sequence star. The pair is about 63 million years old.[4] NamingIn Chinese, {{lang|zh|奎宿}} ({{lang|zh-Latn|Kuí Sù}}), meaning Legs (asterism), refers to an asterism consisting of ν Andromedae, η Andromedae, 65 Piscium, ζ Andromedae, ε Andromedae, δ Andromedae, π Andromedae, μ Andromedae, β Andromedae, σ Piscium, τ Piscium, 91 Piscium, υ Piscium, φ Piscium, χ Piscium and ψ¹ Piscium. Consequently, ν Andromedae itself is known as {{lang|zh|奎宿七}} ({{lang|zh-Latn|Kuí Sù qī}}, {{lang-en|the Seventh Star of Legs}}.)[2] References1. ^{{cite web|title=Nu Andromedae, a blue main-sequence star in Andromeda|url=http://www.astrostudio.org/xhip.php?hip=3881|website=astrostudio.org|accessdate=18 August 2014}}{{dead link|date=February 2018 |bot=InternetArchiveBot |fix-attempted=yes }}
