Pr 0211-c[1] is a Gas Giant exoplanet orbiting around the Sun-like star Pr 0211 a G9 type star. Pr 0211-c along with Pr 0211-b and Pr 0201-b is 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]

Discovery

Pr 0211-c was discovered in 2016 by Luca Malavolta[1][2] 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.
