The newly discovered planet around Pr 0211 is identified as Pr 0211c. It is a massive Jupiter-like planet with at least 7.9 ± 0.2 times the mass of Jupiter, and its orbital period around its host star is greater than 3500 days. Furthermore, Pr 0211c is in a highly eccentric orbit around its host star, with an orbital eccentricity greater than 0.6. The highly eccentric orbit of Pr 0211c could be caused by disruption of the planetary system from close encounters with passing stars as Pr 0211 is a member of an open cluster.
