List of largest exoplanets

Below is a list of the largest exoplanets so far discovered, in terms of physical size, ordered by radius.

The sizes are listed in units of Jupiter radii (RJ, 71 492 km).

This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.

Some well-known planets that are smaller than 1.6 RJ (17.93 R🜨 or 114387.2 km) have been included for the sake of comparison.

Note: Some data may be unreliable or incorrect due to unit or conversion errors This list contains planets with uncertain radii that could be below or above the adopted cut-off of 1.6 RJ, depending on the estimate.

Jupiter as seen by Voyager 1 in 1979. It is the largest planet having its surface resolved [ 1 ] [ 2 ] [ 3 ] and it is the largest planet in the Solar System . [ 4 ]
