OGLE-TR-56 is a dim, distant, magnitude 17 Sun-like star located approximately 1,500 parsecs (4,900 light-years) away in the constellation of Sagittarius. 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. The eclipses were detected by the Optical Gravitational Lensing Experiment (OGLE) team analysing data collected in 2001.
