description Overview

HAT-P-2b

HAT-P-2b is a confirmed gas-giant exoplanet that crosses the disk of its host star, HAT-P-2, an F-type star. It has a mass of about nine Jupiters, completes an orbit in roughly 5.6 days, and follows an unusually eccentric path with an eccentricity near 0.52. The planet was identified by the HATNet transit survey and announced in 2007, making it a useful subject for studying strongly irradiated gia...

WASP-39b
