OGLE-TR-111
Sign in to saveAlso known as OGLE-TR 111
OGLE-TR-111 is a yellow dwarf star approximately 3,600 light-years away in the constellation of Carina (the Keel) with an apparent magnitude of about 17. Because its apparent brightness changes when one of its planets transits, the star has been given the variable star designation V759 Carinae.

OGLE-TR-111 is a yellow dwarf star approximately 3,600 light-years away in the constellation of Carina (the Keel) with an apparent magnitude of about 17. Because its apparent brightness changes when one of its planets transits, the star has been given the variable star designation V759 Carinae.
== Planetary system == In 2002 the Optical Gravitational Lensing Experiment (OGLE) survey detected that the light from the star periodically dimmed very slightly every 4 days, indicating a planet-sized body transiting the star. But since the mass of the object had not been measured, it was not clear that it was a true planet, low-mass red dwarf or something else. In 2004 radial velocity measurements showed unambiguously that the transiting body is indeed a planet.
