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.

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