WR 134 a variable Wolf-Rayet star located about 6,000 light years in Cygnus and is surrounded by a faint Olll bubble nebula. WR 134 classified as an Algol type eclipsing variable with the designation V1769 Cygni, and is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun. WR stars get there name from Charles Wolf and Georges Rayet who discovered their unusual appearance.
