X Carinae

V382 Carinae, also known as x Carinae (x Car), is a yellow hypergiant in the constellation Carina. It is a G-type star with a mean apparent magnitude of +3.93, and a variable star of low amplitude. x Carinae is also one of the rarest, with just 18 known in the Milky Way and six of those in just a single cluster. 
X Carinae is the brightest yellow hypergiant in the night sky, easily visible to the naked eye and brighter than Rho Cassiopeiae although not visible from much of the northern hemisphere. It is 6,200 light years from Earth and around 500 times the radius of the Sun. The large size means that V382 Car is over 200,000 times as luminous as the sun. The low infrared excess suggest that V382 Carinae may be cooling towards a red supergiant phase, less common than yellow hypergiants evolving towards hotter temperatures.
