WASP-19b

WASP-19b is an extrasolar planet. It has one of the shortest orbital periods of any known planet. Its orbital period is approximately 18.932 hours. It is much 1.31 times larger than Jupiter. It orbits the star WASP-19 in the Vela constellation.[1] In December 2013, scientists working with the Hubble Space Telescope found water in the atmosphere of the WASP-19b.[1][2]
