WR 102ka also known as the Peony star is a Wolf-Rayet star that is one of several candidates for the most luminous known star in the Milky Way. The nearer star Eta Carinae which was the second brightest star in the sky for a few years in the 19th century appears to be slightly more luminous than WR 102ka but it is known to be a binary star system.
