HR 5183 b
Description: HR 5183 b is an exoplanet located 102.7 light years away in the constellation of Virgo orbiting the star HR 5183. It has a mass of 3.31 MJ. It has a highly eccentric (e≃0.87) orbit which takes it from within the orbit of Jupiter to beyond the orbit of Neptune which classifies it as an eccentric Jupiter and it has been nicknamed the "whiplash planet". It was discovered in 2019 based on two decades of radial velocity observations.
