'''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 is approximately 1.9 million miles from its star, which is approximately 325 [[light years]] from Earth. It was discovered by Coel Hellier, a professor of astrophysics at the [[Keele University]] in England.<ref>[http://www.breitbart.com/article.php?id=D9AAMKG80&show_article=1 Suicidal planet seems on death spiral into star], breitbart.com, August 26, 2009</ref> |

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 is approximately 1.9 million miles from its star, which is approximately 325 light years from Earth. It was discovered by Coel Hellier, a professor of astrophysics at the Keele University in England.[1]
The closest example of a similar mystery, in our own solar system, is Mars' moon, Phobos. Phobos orbits Mars at a distance of only about 5,600 miles, 40 times closer than our moon is to the Earth.
