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.
Extremes from Earth's viewpoint[]
| Title | Planet | Star | Data | Notes |
|---|---|---|---|---|
| Most distant discovered | SWEEPS-11 / SWEEPS-04 | SWEEPS J175902.67−291153.5 | 27,710 light-years.[1] | Several candidate extragalactic planets have been detected.
The most distant potentially habitable planet confirmed is Kepler-1606b, at 2870 light-years distant,[2] although the unconfirmed planet is over 5,000 light-years distant. |
| Least distant | Proxima Centauri b and c | Proxima Centauri | 4.25 light years | Proxima Centauri b is the closest rocky exoplanet and closest potentially habitable exoplanet known, and c is the closest super-Earth and potentially-ringed planet. As Proxima Centauri is the closest star to the Sun (and will stay so for the next 25,000 years), this is an absolute record. |
| Most distant directly visible | CT Chamaeleontis b | CT Chamaeleontis | 622 light-years[3] | The disputed planet candidate CVSO 30 c may be more distant, at 1,200 light-years. |
| Least distant directly visible | COCONUTS-2b | 35.5 light-years[3] | WISE 1217+1626 B is closer, but is generally considered a brown dwarf. Proxima Centauri c (confirmed in 2020 using archival Hubble data from 1995+) may have been directly imaged.[4] | |
| Star with the brightest apparent magnitude with a planet | Pollux b | Pollux[5] | Apparent magnitude is 1.14 | Aldebaran 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.[6] As of 2021, a candidate planet around Vega has been detected.[7] |
| Star with the faintest apparent magnitude with a planet | Apparent magnitude is 44.61[3] | |||
| Largest angular distance separation from its host star | COCONUTS-2b | 594 arcseconds[8] |
