In 2002 the Optical Gravitational Lensing Experiment (OGLE) detected periodic dimming in the star's light curve indicating a transiting, planetary-sized object.
[3] 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 radius of the planet is only 9% larger than Jupiter's, despite the heating effect by the star.
Planets of its kind are sometimes called "super-hot Jupiters".
