Pr0211 b[2] (also written Pr 0211 b)[1] is a gas giant exoplanet orbiting around the Sun-like star Pr0211, a G-type main sequence star. Pr0211 b along with Pr0201 b are notable for being the first exoplanets discovered in the Beehive cluster located in the constellation Cancer.[1][2]

Discovery

Pr0211 b and Pr0201 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]
