It is an inflated planet, one of the "puffiest planets" known, as a result of its close orbiting distance with its parent star. It has a radius 1.37 times that of Jupiter, but only 19% of its mass. It was discovered in 2016.[1] References1. ^1 2 3 4 https://arxiv.org/pdf/1607.01755v1.pdf {{2016 in space}}{{exoplanet-stub}} 2 : Exoplanets|Exoplanets discovered in 2016 |
