OGLE-TR-10 is a distant, magnitude 16 star in the constellation of Sagittarius. It is located near the Galactic Center.^[1] This star is listed as a eclipsing type variable star with the eclipse due to the passage of the planet as noted in the discovery papers.^[3]

Planetary system

This star is home to OGLE-TR-10b, a transiting planet found by the Optical Gravitational Lensing Experiment (OGLE) survey in 2002.^[3][4]
