From Wikipedia, the free encyclopedia
HD 111232 b is an extrasolar planet that orbits at almost 2 AU with a minimum mass of 6.8 times that of Jupiter. This planet was discovered in the La Silla Observatory by Michel Mayor using the CORALIE spectrograph on 30 June 2003, along with six other planets, including HD 41004 Ab, HD 65216 b, HD 169830 c, HD 216770 b, HD 10647 b, and HD 142415 b.[2]
