The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away. The first confirmed exoplanet discovered in the Proxima Centauri system was Proxima Centauri b, in 2016. HD 219134 (21.6 ly) has six exoplanets, the highest number discovered for any star within this range.
In July, 2014, NASA announced the determination of the most precise measurement so far attained for the size of an exoplanet ; [79] the discovery of an exoplanet (Kepler-421b) that has the longest known year (704 days) of any transiting planet found so far; [80] and, finding very dry atmospheres on three exoplanets (HD 189733b, HD 209458b, WASP ...
However, Proxima Centauri's classification as a red dwarf casts doubts on the habitability of any exoplanets in its orbit due to low stellar flux, high probability of tidal locking, small circumstellar habitable zones and high stellar variation. Another likely candidate is Alpha Centauri, Earth's nearest Sun-like star system 4.37 light-years away.
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
On 31 March 2022, K2-2016-BLG-0005Lb was reported to be the most distant exoplanet discovered by the Kepler telescope, at 17 000 light-years away. [4] Among rogue planets, the furthest are very likely extragalactic planets within the lensing system SDSS J1004+4112 at 6.3 billion light-years. [5] Least distant: Proxima Centauri b: Proxima Centauri
The following list includes some of the potentially habitable exoplanets discovered so far. It is mostly based on estimates of habitability by the Habitable Worlds Catalog (HWC), and data from the NASA Exoplanet Archive. The HWC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo. [1]
The number of known exoplanets officially passed 5,000 on Monday, with NASA confirming the discovery of 65 new worlds. Do you want to hear what that...sounds like?Created by Toronto-based ...
