WASP-76, also known as BD+01 316, is a yellow-white main sequence star in the constellation of Pisces. A suspected stellar companion at a projected separation of 85 astronomical units was reported in 2014.
After about five billion years, WASP-76 has expanded and become more luminous than at the start of its main sequence life, but most probably has not yet reached the subgiant branch.
