OGLE-TR-132 b


OGLE-TR-132 b is an extrasolar planet orbiting star OGLE-TR-132.

In 2003 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object. 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.

The planet has a mass 1.19 times that of Jupiter. Since the planet's inclination is known, the value is exact. It orbits the star (OGLE-TR-132) in an extremely close orbit, even closer than the famous planets 51 Pegasi b and HD 208459 b. The planet races around the star every 1 day 16.6 hours. Interestingly, radius of the planet is only 13% larger than Jupiter's, despite the heating effect by the star. Planets of its kind are sometimes called "super-hot Jupiters".
