Eta Carinae

http://en.wikipedia.org/wiki/Eta_Carinae

Eta Carinae has the names Tseen She (from the Chinese 天社 [Mandarin:tiānshè] "Heaven's altar") and Foramen.[30] It is also known as 海山二 (Hǎi Shān èr, English: the Second Star of Sea and Mountain),[31] referring to Sea and Mountain, an asterism that Eta Carinae forms with s Carinae, λ Centauri and λ Muscae.[32]

One remarkable aspect of Eta Carinae is its changing brightness. It is currently classified as a luminous blue variable (LBV) binary star due to peculiarities in its pattern of brightening and dimming.
