Because of its distance of about 1170 light years,[8] and location in a crowded field it was not notable in any way. Spectral type of the star is type K dwarf star, slightly cooler and less luminous than the Sun.[2] Planetary systemHowever, in 2002 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object.[13] 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-113b. {{OrbitboxPlanet begin}}{{OrbitboxPlanet| exoplanet = b | mass = 1.32 ± 0.19 | period = 1.4324757 ± 0.0000013 | semimajor = 0.0229 ± 0.0002 | eccentricity = 0 }}{{Orbitbox end}} See also
