Pr0201 b

Pr0201 b[1] (also written Pr 0201 b)[2] is an exoplanet orbiting around the F-type main sequence star Pr0201. Pr0201 b along with Pr0211 b are notable for being the first exoplanets discovered in the Beehive Cluster located in the constellation Cancer.[2][1] Since Pr0201 b has a mass of about 0.5 Jupiters and an orbital period of about 4 days, it is likely a hot Jupiter.
