A light curve for OGLE-TR-10 showing the planet transit, adapted from Pont et al. (2007)

OGLE-TR-10 is a distant G-type main sequence star located 4100 light years from Earth in the constellation of Sagittarius. It is located near the Galactic Center. ^[2] This star is listed as an eclipsing type variable star with the eclipse due to the passage of the planet as noted in the discovery papers. ^[5] The eclipses were detected by the Optical Gravitational Lensing Experiment (OGLE) team analysing data collected in 2001. ^[6]

Planetary system

This star is home to OGLE-TR-10b, a transiting planet found by the Optical Gravitational Lensing Experiment (OGLE) survey in 2002. ^{[5] [7]}
