Table Section Text: The sizes are listed in units of Jupiter radii (RJ, R♃)(71,492km). All planets listed are larger than two times the size of the largest planet in the Solar System, Jupiter.

Exoplanet name	Radius (RJ) (Jupiter = 1)	Notes

Sun (Sol)	9.95 (1,391,400 km)	The largest object in the Solar System. Reported for reference

HD 100546 b's surrounding disk	6.9+2.7 −2.9	Largest exoplanet in the NASA Exoplanet Archive, although because of flux from the planet and the disk that are superimposed, the exact size of this planet cannot be determined and the emitting area has this size, composed of the planet and including its disk, not to be mistaken as a single planet radius.

GQ Lupi b	4.6±1.4, 3.0–6.5	Currently the largest exoplanet discovered. 1 - 36 MJ; at the highest end of this range, it may be classified as a young brown dwarf.

EPIC 203868608 a	2.75±0.05	23.2 MJ; is likely a brown dwarf.

DH Tauri b	2.7±0.8	11+10 −3 MJ; at its largest, it would be classified as a brown dwarf

ROXs 42Bb	2.5	This massive hot jupiter (9+6 −3 MJ) varies from 0.9 RJ to 3 RJ.

OTS 44	2.3–5.7	Very likely a sub-brown dwarf, which it may be the lowest-mass free-floating substellar objects. It is surrounded by a circumstellar disk of dust and particles of rock and ice

Kepler-13 Ab (KOI-13b)	2.216±0.087	Lisa et al gives also radii of 1.512±0.035 RJ and 2.63+1.04 −0.82 RJ. Natalie et al calculate 2.03 RJ.

CT Chamaeleontis b	2.2+0.81 −0.6	17 MJ; is likely a brown dwarf.

KOI-368.01	2.1±0.2

WASP-79b	2.09±0.14

HAT-P-67b	2.085+0.096 −0.071	0.34+0.25 −0.19 MJ; a very puffy Hot Jupiter

XO-6b	2.07±0.22	4.4 MJ; a very puffy Hot Jupiter

HAT-P-32b	2.037±0.999	0.941 (± 0.166) MJ; a very puffy Hot Jupiter. Other estimates give 1.789±0.025 RJ.

KOI-3681.01	2.0+0.7 −1	Orbits fairly close to its 1.1+0.2 −0.2 M☉ star, with 217 day-long years.

WASP-17b	1.991+0.08 −0.58	Was the largest known planet in 2012. At only 0.486 MJ, this Hot Jupiter is extremely low density.

Kepler-435b	1.99±0.18

KOI-680 b	1.99

KELT-19 Ab	1.91

CVSO 30b	1.91

51 Pegasi b (Bellerophon)	1.9±0.3	First exoplanet to be discovered orbiting a main-sequence star. Prototype hot Jupiters.

WASP-12b ("Pitch black")	1.900+0.057 −0.055, 1.736±0.056	This planet is so close to its parent star that its tidal forces are distorting it into an egg shape. As of September 2017, it has been described as "black as asphalt", and as a "pitch black" hot Jupiter as it absorbs 94% of the light that shines on its surface.

KELT-9b	1.891+0.061 −0.055	One of the hottest exoplanets known.

HAT-P-65b	1.89±0.13

WASP-121b	1.865±0.044

KELT-8b	1.86+0.18 −0.16

HATS-23b	1.86+0.3 −0.4

HAT-P-33b	1.827±0.29

Cha 110913-773444	1.8	A rogue planet (Likely a sub-brown dwarf) that is surrounded by a protoplanetary disk. It is one of youngest free-floating substellar objects with 0.5–10 Myr.

TrES-4	1.799±0.063	This planet has a density of 0.2 g/cm3, about that of balsa wood, less than Jupiter's 1.3g/cm3

WASP-122b	1.792±0.069

KELT-12b	1.78+0.17 −0.16

HATS-26b	1.75±0.21
