List of exoplanet extremes

The following are lists of extremes among the known exoplanets. The properties listed here are those for which values are known reliably. The study of exoplanets is one of the most dynamic emerging fields of science, thus these values may change as new discoveries are made.

Extremes from Earth's viewpoint

Title	Planet	Star	Data	Notes
Most distant discovered	SWEEPS-11 / SWEEPS-04	SWEEPS J175902.67−291153.5 / SWEEPS J175853.92−291120.6	light-years	Assuming the largest distance from the microlensing light-curve, the planet OGLE-2017-BLG-0364Lb might be more distant, at around light-years. PSR J0738-4042 at light-years was shown to be affected by a disk of asteroids, but no planets have been detected yet. The most distant potentially habitable planet confirmed is Kepler-1606b, at 2870 light-years distant, although the unconfirmed planet KOI-5889.01 is over 5000 light-years distant. On 31 March 2022, K2-2016-BLG-0005Lb was reported to be the most distant exoplanet discovered by the Kepler telescope, at light-years away. Among rogue planets, the furthest are very likely extragalactic planets within the lensing system SDSS J1004+4112 at 6.3 billion light-years.
Least distant	Proxima Centauri d		4.25 light-years	Proxima Centauri b is the closest potentially habitable exoplanet known. As Proxima Centauri is the closest star to the Sun, this is an absolute record, unless a closer brown dwarf/compact object with a planet is discovered. In about 25000 years Alpha Centauri AB will be closer to the Sun than its companion Proxima Centauri. If no companion is confirmed around these two stars, no closer brown dwarf/compact object with a planet is found and no planet is found around either Ross 248 or Gliese 445, the least distant record will change in a bit less than 80000 years from now, making Ross 128 b, a "temperate exoplanet in the inner edge of the habitable zone" the least distant one.
Most distant directly visible	CT Chamaeleontis b	CT Chamaeleontis	622 light-years	The resolved likely close to equal mass binary brown dwarf NIRISS-NGC1333-10 AB, the mass of NIRISS-NGC1333-10 B is slightly higher than the deuterium burning limit, is more distant at 978 light-years. The disputed planet CVSO 30 c may be more distant, at 1165 light-years away. The candidate planet AT Pyxidis b may also be more distant, at ~1207 light-years away. Among rogue planets, o005 s41280 is the most distant at light-years; followed by A2744-BD-1 and o006 s00089, at and 6520 light-years away, respectively. As free-floating objects, all of them might not be considered as planets, although their masses might be below 13 M_J.
Closest directly visible	Epsilon Indi Ab	Epsilon Indi	12.05 light-years	next closest directly visible. WISE 0855-0714 is closer, at about 7.4 light-years away. As a free-floating object, it might not be considered as planet, although its mass is below 13 M_J. The planet Alpha Centauri Ab is also closer and might have been directly imaged.
Closest Hot Jupiter type exoplanet to Earth	Upsilon Andromedae b	Upsilon Andromedae A
Closest Super Jupiter type exoplanet to Earth	Epsilon Indi Ab	Epsilon Indi
Closest Super Earth type exoplanet to Earth	Proxima Centauri b	Proxima Centauri
Star with the brightest apparent magnitude with a planet	Alpha Arietis b	Hamal	Apparent magnitude is 2.005	Alpha Centauri A has a directly imaged candidate planet. The evidence of planets around Vega with an apparent magnitude of 0.03 is strongly suggested by circumstellar disks surrounding it., a candidate planet around Vega has been detected. Aldebaran was thought to have a candidate planet, however later studies found the existence of the planet dubious. Similarly, Pollux and Mirfak were claimed to have orbiting planets, all of which have been either questioned or disproved. An Earth-mass planet claimed to orbit Alpha Centauri B was subsequently refuted. A 2023 study detected 10 luminous point sources around the primary star of Fomalhaut system, of which the last source may or may not be a planetary-mass companion. This star was previously thought to harbour a directly imaged planet named Fomalhaut b, before the realization of object as an expanding debris cloud from a planetesimal collision.
Star with the faintest apparent magnitude with a planet	MOA-bin-29Lb	MOA-bin-29L	Apparent magnitude is 44.61
Closest planet to the celestial north pole	TOI-1691 b	TOI-1691	Declination of
Closest planet to the celestial south pole	HD 110082 b	HD 110082	Declination of
Star with the highest apparent motion with a planet	Barnard planets	Barnard's Star	10.358 arcsec/yr	As Barnard's Star has the highest apparent motion in the sky, this is currently an absolute record.
Largest angular distance separation from its host star	COCONUTS-2b	COCONUTS-2	594 arcseconds	A candidate planet or brown dwarf around BD+29 5007 has an even larger angular separation of about 935 arcseconds.
Smallest resolved angular distance separation from its parent star	Beta Pictoris c	Beta Pictoris	0.138 arcseconds	Derived from its separation of ~ and its distance of 63.4 light-years.
Smallest angular distance separation from its parent star	NGC 6440 X-2 b	NGC 6440 X-2	0.31 microarcseconds	Derived from its separation of and its distance of ~ light-years.
Star with the largest apparent size	Alpha Arietis b	Hamal		Accounted for the limb darkening effect. Several stars have a larger angular diameter and were claimed to have candidate planets: Aldebaran, L2 Puppis and Alpha Centauri A.
