Pr0211 c,[1] sometimes written as Pr 0211 c, is a gas giant exoplanet orbiting around the Sun-like star Pr0211, a G-type main sequence star. Pr0211 c and two other planets, Pr0211 b and Pr0201 b are notable for being one of the first exoplanets discovered in the Beehive cluster located in the constellation Cancer, and for being the first multi-planet system discovered in an open cluster.[1] Its host star, Pr0211, is rotationally variable and has a rotation period of 7.97 days.[2]

Discovery[]

Pr0211 c was discovered in 2016 by [1][3] and his colleagues while observing its host star with the HARPS-N spectrograph on the 3.6 metres (12 ft; 3.9 yd) Italian Telescopio Nazionale Galileo (TNG) in La Palma, and the Tillinghast Reflector Echelle Spectrograph (TRES) mounted at the 1.5 metres (4.9 ft; 1.6 yd) telescope at the University of Georgia in the United States.
