OGLE-TR-132 is a distant magnitude 15.72 star in the star fields of the constellation Carina. Because of its great distance, about 4900 light years, and location in the crowded field it was not notable in any way. Spectral type of the star is type F yellow-white very metal rich dwarf star, slightly hotter and more luminous than the Sun.

Planetary system[edit]

However, in 2003 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object.[1] Since low-mass red dwarfs and brown dwarfs may mimic a planet radial velocity measurements were necessary to calculate the mass of the body. In 2004 the object was proved to be a new transiting extrasolar planet, OGLE-TR-132 b.[3]
