}} is an exoplanet orbiting around the F-type main-sequence star Pr0201. Pr0201 b along with Pr0211 b are notable for being the first exoplanets discovered in the Beehive Cluster located in the constellation Cancer. Since Pr0201 b has a mass of about half of Jupiter and an orbital period of about 4 days, it is likely a hot Jupiter. Its host star, Pr0201, is rotationally variable and has a rotation period of 5.63 days.{{cite journal|bibcode= 2014MNRAS.442.2081K|title= Stellar rotational periods in the planet hosting open cluster Praesepe|last1= Kovács|first1= Géza|last2= Hartman|first2= Joel D.|last3= Bakos|first3= Gáspár Á.|last4= Quinn|first4= Samuel N.|last5= Penev|first5= Kaloyan|last6= Latham|first6= David W.|last7= Bhatti|first7= Waqas|last8= Csubry|first8= Zoltán|last9= De Val-Borro|first9= Miguel|journal= Monthly Notices of the Royal Astronomical Society|year= 2014|volume= 442|issue= 3|page= 2081|doi= 10.1093/mnras/stu946|doi-access= free|arxiv= 1405.3728}}
