Below is a list of the largest known exoplanets in terms of radius and size.
List
The sizes are listed in units of Jupiter radii (RJ , R♃). All planets lists are larger than the largest planet of our Solar System, Jupiter.
Timeline of largest exoplanet recordholders
Planet | Size (RJ) | Date | Notes | |
---|---|---|---|---|
HAT-P-32b | 2.02 | 2013— | CT Cha b may be larger at 2.2 Jupiter radii, but its status as a planet or brown dwarf is unconfirmed | |
WASP-17b | 1.991 | 2007—2009 | ||
TRES-4b | 1.67 | 2007—2009 | This planet has a density of 0.2 g/cm3, about that of balsa wood, less than Jupiter's 1.3g/cm3 It was succeeded by WASP-17b as the largest exoplanet./>[5][6] |
