1 Mins read



Dimitar Sasselov – in 2002 sighted the farthest planet from the Earth discovered until then – OGLE-TR-56b.


Use in industry

OGLE-TR-56b is an extrasolar planet located approximately 1500 parsecs 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 planet is theorized to have iron rain.[5]
