HIP 67522 is a G-class star which, by comparison with the Sun, is slightly larger (1.38 R☉) and cooler (5675 K versus 5772 K for the Sun). It lies about 127 parsecs away in the constellation Centaurus. Its visual magnitude of 9.8 makes it much too faint to be seen by the unaided eye.[3]
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.[4]
