Pr0201 b[2] (also written Pr 0201 b)[1] 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 0.5 Jupiters and an orbital period of about 4 days, it is likely a hot Jupiter.

Discovery

Pr0201 b and Pr 0211 b were discovered in 2012 by Sam Quinn[1][2][3] and his colleagues while observing 53 stars in the Beehive cluster using the 1.5 metres (4.9 ft; 1.6 yd) telescope at the University of Georgia in the United States.[1]
