WASP-1b is an extrasolar planet orbiting the star WASP-1 located over 1000 light-years away in the constellation Andromeda. The planet's mass and radius indicate that it is a gas giant with a similar bulk composition to Jupiter. Unlike Jupiter, but similar to many other planets detected around other stars, WASP-1b is located very close to its star, and belongs to the class of planets known as hot Jupiters. In recognition of the regional support given to the project on La Palma, the discoverers gave the planet the alternative designation Garafia-1.
