OGLE-TR-10
Star in the constellation Sagittarius
From Wikipedia, the free encyclopedia
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.[3] 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.[8] The eclipses were detected by the Optical Gravitational Lensing Experiment (OGLE) team analysing data collected in 2001.[9]
