WASP-18b is an extrasolar planet that is notable for having an orbital period of less than one day, and is expected to eventually collide into its star WASP-18, perhaps in about a million years. The planet was discovered by Coel Hellier, a professor of astrophysics at the Keele University in England.[1]
