Below is a list of records that have been set by extrasolar planets.
Planets[]
| Title | Planet | Star | Data | Notes |
|---|---|---|---|---|
| Most distant | SWEEPS-04 / SWEEPS-11 | SWEEPS J175902.67-291153.5 / SWEEPS J175853.92-291120.6 | 27,700 light years | An analysis of the lightcurve of the microlensing event PA-99-N2 suggests the presence of a planet orbiting a star in the Andromeda Galaxy. In late January 2018, a team of scientists led by Xinyu Dai claimed to have discovered a collection of about 2,000 rogue planets in the quasar microlens RX J1131-1231, which is 3.8 billion light-years distant. The bodies range in mass from that of the Moon to several Jupiter masses. |
| Most distant potentially habitable planet | Kepler-1606b | Kepler-1606 | 2,870 light years | An unconfirmed potentially habitable planet, KOI-5889.01, is located over 5,000 light years away. |
| Least distant | Proxima Centauri b, c, and d | Proxima Centauri | 4.2 light years | These are the closest extrasolar planets, b and d are the closest rocky planets, while c is the closest mini-Neptune and potentially ringed planet. b is the closest potentially habitable planet. |
| Least distant giant planet | Epsilon Eridani b | Epsilon Eridani | 10 light years | |
| Most distant which is directly visible | CVSO 30 c | CVSO 30 | 1,200 light years | Also is the first directly imaged planet in system with a transiting planet. However, this is a disputed planet candidate - the most distant directly visible confirmed is CT Chamaeleontis b. |
| Closest directly visible | COCONUTS-2b | COCONUTS-2 | 35.5 light years | |
| Star with the brightest apparent magnitude with a planet | Pollux b | Pollux | Apparent magnitude of this star is 1.14 | Aldebaran, with an apparent magnitude of 0.75-0.95, has a disputed planet candidate. The evidence of planets around Vega with an apparent magnitude of 0.03 is strongly suggested by circumstellar disks surrounding it. A planetary candidate around Vega has been detected. |
| Star with the brightest apparent magnitude with a planet | GU Piscium b | GU Piscium | 42 arc seconds | The evidence of planets around Vega with an apparent magnitude of 0.03 is strongly suggested by circumstellar disks surrounding it. As of 2013, no planets had yet been confirmed. |
| Star with the faintest apparent magnitude with a planet | MOA-bin-29Lb | MOA-bin-29L | Apparent magnitude is 44.61. | |
| Most massive | HR 2562 b | HR 2562 | 30 ± 15 Jupiter masses | According to most definitions of planet, it may be too massive to be a planet, and may be a brown dwarf instead. |
| Least massive | PSR B1257+12 A | PSR B1257+12 | >0.02 Earths | Only twice as massive as the Moon. Mass of PSR B1257+12 A is based on an assumption of coplanarity with the outer two planets. The least massive exoplanet for which a true mass is known is Kepler-138b, at 0.07 Earth mass. Kepler-37b may be less massive (assuming Moon-like density), estimated mass >0.01 Earth mass, < 6 Earth mass |
| Largest radius | GQ Lupi b | GQ Lupi | 3.0 ± 0.5 Jupiter radii | The emitting area of the extremely young HD 100546 b, including planet and disk, indicates that there is a large amount of heat left from formation. Over time, the planet will shrink to approximately the size of Jupiter. This candidate could be larger. |
| Smallest radius | Kepler-37b | Kepler-37 | 0.296 Earth radius | Some planetesimals, such as SDSS J1228+1040 b and WD 1145+017 b, are smaller. |
| Most dense | Kepler-131c | Kepler-131 | 77.7 g/cm3. | This number is highly uncertain. |
| Least dense | Kepler-51c | Kepler-51 | ~ 0.03 g/cm3. | Some of the other planets in this star system have a similar density. |
| Hottest | KELT-9b | KELT-9 | 4050 K (3777 °C; 6830 °F) | A disputed planetary candidate, Kepler-70b, may be hotter at 7000 K (6726 °C; 12140 °F) |
| Coldest | OGLE-2016-BLG-1195Lb | OGLE-2016-BLG-1195L | 31 K (-242 °C; -403 °F) | |
| Highest albedo | Kepler-1658b | Kepler-1658 | 0.758 (geometric albedo) | |
| Lowest albedo | TrES-2b | GSC 03549-02811 | Geometric albedo < 1% | |
| Youngest | Proplyd 133-353 | Proplyd 133-353 | ~500,000 years | |
| Oldest | PSR B1620-26 b | PSR B1620-26 | ~13 billion years old | Orbits in a circumbinary orbit around two stellar remnants - a pulsar and a white dwarf. Kapteyn b is the oldest potentially habitable exoplanet at 11 billion years. |
| Longest orbital period | COCONUTS-2b | COCONUTS-2 | 1,100,000 years | |
| Shortest orbital period | SWIFT J1756.9-2508 b | SWIFT J1756.9-2508 | 48 minutes, 56.5 seconds | K2-137b has the shortest orbit around a main-sequence star, at 4.31 hours. |
