Hot Jupiter orbiting OGLE-TR-56

OGLE-TR-56b is an extrasolar planet located approximately 1500 parsecs or 5000 light years away in the constellation of Sagittarius, orbiting the star OGLE-TR-56. This planet was the first known exoplanet to be discovered with the transit method. The object was discovered by the OGLE project, announced on July 5, 2002[2] and confirmed on January 4, 2003 by the Doppler technique.[3] The period of this confirmed planet was the shortest until the confirmed discovery of WASP-12b on April 1, 2008.[4] The short period and proximity of the OGLE-TR-56 b to its host mean it belongs to a class of objects known as hot Jupiters.

The radial velocity trend of OGLE-TR-56, caused by the presence of OGLE-TR-56 b.

The planet is thought to be only 4 stellar radii from its star, and hot enough to have iron rain.[5]
