HIP 67522 is a G-type main sequence star located at a distance of 407 light-years (125 parsecs) away in the constellation of Centaurus. Its visual magnitude of 9.8 makes it much too faint to be seen by the unaided eye. It is slightly larger than the Sun (1.38 R☉) but cooler (5,675 K versus 5,772 K for the Sun). It is also very young being only around 17 million years old. It has two exoplanets orbiting it.[4]
Planetary system
Two exoplanets, HIP 67522 b and HIP 67522 c, are known to orbit the star and transit its face as seen from Earth. Their orbital periods are much less than Mercury's 88 days around the Sun, being 6.96 days for b and 14.33 days for c.[7]
Detections of frequent flaring of the star during the transit phase of the innermost planet (HIP 67522b) suggest that interacts with the stars magnetic field producing the high rate of flares.[8]
