OGLE-TR-56b is an
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 planet is thought to be only 4 stellar radii from its star, and hot enough to have iron rain.[5]
