List of largest exoplanets

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.

3.77[18] | Template:Asterisk | 20 ± 10;[19] Template:Nowrap[20] |
First confirmed exoplanet candidate to be directly imaged. GQ Lupi b has a mass of 1 – Template:Val; in the higher half of this range, it may be classified as a young brown dwarf. It should not be confused with the star GQ Lup C (2MASS J15491331), 2400 AU away, sometimes referred to as GQ Lup B.[21] Other sources of the radius include Template:Val Template:Jupiter radius,[22] Template:Val Template:Jupiter radius,[20] Template:Val Template:Jupiter radius,[23] 4.6 ± 1.4 RJ, 6.5 ± 2.0 RJ.[24] | |
| HD 100546 b (KR Muscae b) |
3.4[25] | Template:Asterisk | 25[25] | Sometimes the initially reported Template:Val Template:± Template:Jupiter radius for the emitting area due to the diffuse dust and gas envelope or debris disk surrounding the planet[26] is confused with the actual radius. Other source of mass: 1.65 Template:Val.[27] HD 100546 (KR Mus) is the nearest Herbig Be star to the Sun.[28] | |
| 2MASS J0437+2331 | 3.30[29]Template:Efn | Template:Dagger | 7.1 Template:±[29] | May be a sub-brown dwarf or a rogue planet | |
| OTS 44 | 3.2Template:Snd3.6[30] | Template:Dagger | 11.5[31] | First discovered rogue planet; very likely a brown dwarf[32] or sub-brown dwarf.[33] It is surrounded by a circumstellar disk of dust and particles of rock and ice. The currently preferred radius estimate is done by SED modelling including substellar object and disk model.[30] | |
| 2MASS J044144b (2M 0441+23 Bb) |
3.06[34]Template:Efn | Template:Dagger | 9.8 ± 1.8[34] | Based on the mass ratio to 2M J044145 A (2M 0441+23 Aa) it is likely not a planet according to the IAU's exoplanet working definition.[35] Part of the lowest mass quadruple 2M 0441+23 system of Template:Solar mass.[34] | |

| AB Aurigae b (AB Aur b) |
< 2.75[38]Template:Efn | ! | 20 Template:Nowrap,[39] Template:Nowrap Template:Nowrap, < 130[38] |
Likely a brown dwarf; Assuming a hot-start evolution model and a planetary mass, AB Aurigae b would be younger than 2 Myr to have its observed large luminosity, which is inconsistent with the age of AB Aurigae of 6.0 Template:± Myr, which could be caused by delayed planet formation in the disk.[40] Other system ages include 1 - 5 Myr,[38] 4 ± 1 Myr[41] and 4 Myr.[42] Another source gives a higher mass of Template:Val in the brown dwarf regime for an age of 4 Myr, arguing since gravitational instability of the disk (preferred formation mechanism in the discovery publication)[38] operates on very short time scales, the object might be as old as AB Aur.[39] A more recent study also support the latter source, given the apparent magnitude was revised upwards.[43] | |

First exoplanet to be imaged by the James Webb Space Telescope.[176] The JWST direct imaging observations tightly constrained its bolometric luminosity, which provides a robust mass constraint of 7.1 ± 1.2 Template:Jupiter mass. The atmospheric fitting of both temperature and radius are in disagreement with evolutionary models. Moreover, this planet is around 14 million years old which is however not associated with a debris disk, despite its young age,[177][178] causing it to not fit current models for planetary formation.[179] | |

Coldest and smallest known star hosting exoplanets.[195] All seven exoplanets are rocky planets, orbiting closer to the star than Mercury. Their orbits' inclinations of 0.1 degreesTemplate:Sfn makes TRAPPIST-1 system the flattest planetary system.[196] Age: 7.6 ± 2.2 Gyr.[197] Reported for reference. | |

Such the rich cobalt blue[201][202] colour of HD 189733 Ab may be the result of Rayleigh scattering. The wind can blow up to Template:Convert from the day side to the night side.[203] | |
| 2M1207 b (TWA 27b) |
1.13[204] | Template:Dagger | 5.5 ± 0.5[204] | First planetary body discovered via direct imaging, and the first around a brown dwarf.[205][206] It could be considered a sub-brown dwarf due to its large mass in relation to its host: 2M1207 b is around six times more massive than Jupiter, but orbits a Template:Jupiter mass brown dwarf, a ratio much larger than the 1:1000 of Jupiter and Sun for example. The IAU defined that exoplanets must have a mass ratio to the central object less than 0.04,[207][208] which would make 2M1207b a sub-brown dwarf. Nevertheless, 2M1207b has been considered an exoplanet by press media and websites,[209][210][211] exoplanet databases[212][213] and alternative definitions.[214] It will shrink to a size slightly smaller than Jupiter as it cools over the next few billion years. | |

1.11[218] | ← | 10.5[219] | This exoplanet has the largest observed host star separation of any known exoplanet, at 12 000 AU (0.058 pc; 0.19 ly) and the longest known orbital period, at a duration of 1.27 Myr. First confirmed and third discovered circumtriple planet. | |
| CoRoT-3 Ab | 1.08 ± 0.05[220] | Template:Asterisk | 21.66 ± 1.00[221] | Might be considered either a planet or a brown dwarf, depending on the definition chosen for these terms. If the brown dwarf/planet limit is defined by mass regime using the deuterium burning limit as the delimiter (i.e. Template:Val), CoRoT-3b is a brown dwarf.[222] If formation is the criterion, CoRoT-3 Ab may be a planet given that some models of planet formation predict that planets with masses up to 25–30 Jupiter masses can form via core accretion.[223] However, it is unclear which method of formation created CoRoT-3A b. | |
| Kepler-1647 b | 1.05932 ± 0.01228[224] | ← | 1.52 ± 0.65[224] | Longest transit orbital period of any confirmed transiting exoplanet discovered at the duration of 1107 days[225] and largest circumbinary planet discovered.[226] This planet is located within the habitable zone of binary star system Kepler-1647 and thus could theoretically have a habitable Earth-like exomoon.[227] | |
| Kepler-90h | 1.01 ± 0.09[228] | ← | 0.639 ± 0.016[229] | Located in the Kepler-90 system with eight known exoplanets, whose architecture is similar to that of the Solar System, with rocky planets being closer to the star and gas giants being more distant. This planet is located at 1 AU from its star, which is within the habitable zone of Kepler-90 and thus could theoretically have a habitable Earth-like exomoon. | |
| Ahra (WD 0806-661 b) |
1.007 – 1.04[230] | ← | 6.8 – 9.0[230] | First exoplanet discovered around a single (as opposed to binary) white dwarf, and the coldest directly imaged exoplanet when discovered.[231] Possibly formed closer to Maru (WD 0806−661) when it was a main sequence star, this object migrated further away as it reached the end of its life (see stellar evolution), with a current separation of about Template:Val. Might be considered an exoplanet or a sub-brown dwarf, the dimmest sub-brown dwarf. The IAU considers objects below the Template:Val limiting mass for deuterium fusion that orbit stars (or stellar remnants) to be planets, regardless on how they formed.[232] | |

As expected, Dimidium is larger than Poltergeist, whether one of the additional planets found till 1999 is larger than Dimidium is not clear to this day. | |
| 1995Template:Snd1999 | Dimidium (51 Peg b) |

| (1993Template:Snd1995) | PSR B1620−26 b (PSR B1620-26 (AB) b, "Methuselah") |
Unknown | → | 2.5 ± 1[267] | Likely larger than Poltergeist, but not confirmed as planet until 2003. First circumbinary planet, first planet to be found in a globular cluster and the oldest planet to be discovered (until 2020) at the age of 11.2–12.7 billion years old,[268] hence the nickname, "Methuselah".[267][269] | |

Unknown | ← | 0.013 53 ± 0.000 63 (4.3 ± 0.2 Template:Val)[270] |
First confirmed planet ever discovered outside the Solar System together with the less massive Draugr (PSR B1257+12 b), one of three pulsar planets known to be orbiting the pulsar Lich (PSR B1257+12).[271][272] Unclear whether Lich planets are survivors or formed in a second round of planet formation from the remnants of the supernova. | |
| (1989Template:Snd1995) | HD 114762 Ab ("Latham's Planet") |
Unknown | * | Template:Nowrap[273] ~63.2[274] |
Discovered in 1989 by Latham to have a minimum mass of 11.069 ± 0.063 Template:Val (at 90°) and a probable mass of approximately Template:Val (at 10°),[274] making the former planet the first to be spotted,[275] and confirmed in 1991, it was thought to be the first discovered exoplanet until 2019 when it was confirmed to be a low-mass star with the mass of 147.0 Template:± Template:Val,[276] making the planet above the first confirmed exoplanet discovered ever. | |
| (1988Template:Snd1992) | Tadmor (Gamma Cephei Ab, γ Cep Ab) |
Unknown | → | 6.6 Template:±[277] | First evidence for exoplanet to receive later confirmation. First reported in 1988,[278] making it arguably the first true exoplanet discovered, and independently in 1989,[279] however, retracted in 1992[280] due to the possibility that the stellar activity of the star mimics a planet not allowing a solid discovery claim and then finally confirmed in 2003.[281] | |

Oldest, largest and most massive planet in the Solar System[234] Observations date back to 7th or 8th century BC. Using an early telescope the Galilean moons were discovered in 1610, the planet hosts 95 known moons. Reported for reference. | |
