List of largest exoplanets
Below is a list of the largest exoplanets so far discovered, in terms of physical size, ordered by radius. The exoplanets with sizes higher than 1.5 jupiter radii are included.
List
The sizes are listed in units of Jupiter radii (RJ, R♃). All planets listed are larger than the largest planet in the Solar System, Jupiter.
This list is incomplete; you can help by expanding it.
