Template:Short description

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]

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

Limitations

This list of extrasolar objects may and will change over time due to diverging measurements published between scientific journals, varying methods used to examine these objects, and the notably difficult task of discovering extrasolar objects in general. These objects are not stars, and are quite small on a universal or even stellar scale. Then there is the fact that these objects might be brown dwarfs, sub-brown dwarfs, or not exist at all. Because of this, this list only cites the most certain measurements to date and is prone to change.

List

The sizes are listed in units of Jupiter radii (Template:Jupiter radius, 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 Template:Jupiter radius (17.93Template:NbspTemplate:Earth radius or Template:Val Template:Val) have been included for the sake of comparison.

Key (classification)
Template:Asterisk Probably brown dwarfs (≳ 13 Template:Jupiter mass) (based on mass)
Template:Dagger Probably sub-brown dwarfs (based on mass and location)
? Uncertain status (inconsistency in age or mass of planetary system)
! Uncertain status while probably brown dwarfs (≳ 13 Template:Jupiter mass) (based on mass)
Probably exoplanets (≲ 13 Template:Jupiter mass) (based on mass)
Planets with grazing transit, hindering radius determination
Template:Number sign Notable non-exoplanets reported for reference

Candidates for largest exoplanets

Unconfirmed exoplanets

These planets are also larger than 1.6 times the size of the largest planet in the Solar System, Jupiter, but have yet to be confirmed or are disputed.
Note: Some data may be unreliable or incorrect due to unit or conversion errors

Exoplanets with uncertain radii

This list contains planets with uncertain radii that could be below or above the adopted cut-off of Template:Jupiter radius, depending on the estimate.

Key (classification)
Probably planets (≲ 13 Template:Jupiter mass) (based on mass)
? Status uncertain (inconsistency in age or mass of planetary system)

Chronological list of largest exoplanets

These exoplanets were the largest at the time of their discovery.

Key (classification)
Template:Asterisk Later identified to be a probable/confirmed brown dwarf (≳ 13 Template:Jupiter mass) or a star (≳ 82.76 Template:Jupiter mass)
Template:Dagger Candidate for largest exoplanet (currently or in time span)
? Status uncertain (inconsistency in age or mass of planetary system) while being candidate for largest exoplanet
Assumed largest exoplanet, while unconfirmed, later retracted or later confirmed
Largest exoplanet (≲ 13 Template:Jupiter mass) at the time
Largest confirmed exoplanet (in radius and mass), while discovered candidates might be larger
