Best Low Density
WASP-107b is an exoplanet orbiting a K-type star. It’s a super-Neptune with a remarkably low density, making it one of the least dense planets discovered to date. Observations reveal significant helium escaping from its atmosphere. This planet is of interest to astronomers studying planetary formati...
WASP-17b is a giant exoplanet announced in 2009 by the Wide Angle Search for Planets consortium. It holds the distinction of being the first exoplanet confirmed to orbit in a retrograde direction, moving in the opposite direction of its host star's rotation. Classified as a hot Jupiter, it is also n...
WASP-127b is a transiting exoplanet classified as a "hot Saturn" due to its mass being roughly equivalent to Saturn's, despite being significantly larger in radius. Discovered in 2016, it orbits a G-type star and possesses a heavily inflated, low-density atmosphere. Spectroscopic observations have s...
HAT-P-32b is an inflated hot Jupiter exoplanet orbiting the G-type or F-type star HAT-P-32. Discovered in 2011, it is situated in the northern constellation of Andromeda. The planet has one of the largest known radii for its mass class, resulting in an extremely low density. Its significant atmosphe...
