It is rotationally variable and has a rotation period of 7.97 days,[5] with its spin axis at an inclination of 76°±11° to the plane of the sky.
[6][7][8] Pr0211 b is a gas giant exoplanet, specifically a hot Jupiter, orbiting around Pr0211.
[9][10] Pr0211 b and Pr0201 b were discovered in 2012 by Sam Quinn[9][10][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.
[11] Pr0211 c was discovered in 2016 by Luca Malavolta[11][4] 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.
