Pr0211 b
Pr0211 b[1] (also written Pr 0211 b)[2] is a gas giant exoplanet orbiting around the Sun-like star Pr0211 (2MASS J08421149+1916373), 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.[2][1] Its host star, Pr0211, is rotationally variable and has a rotation period of 7.97 days.[3]

Discovery
Pr0211 b and Pr0201 b were discovered in 2012 by Sam Quinn[2][1][4] 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.[2] Another planet (Pr0211 c) in the same star system was discovered in 2016.[5]
