    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. [1] [2] Since Pr0201 b has a mass of about half of Jupiter and an orbital period of about 4 days, it is likely a hot Jupiter. Its host star, Pr0201, is rotationally variable and has a rotation period of 5.63 days. [3]

    Discovery

    Pr0201 b and Pr 0211 b were discovered in 2012 by Sam Quinn [1] [2] [4] and his colleagues while observing 53 stars in the Beehive Cluster using the 1.5  m (4.9  ft ; 1.6  yd ) telescope at the University of Georgia in the United States. [2]
