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

[edit]

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]
