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]
This list is incomplete, currently containing 34 exoplanets, 11 of which probably lie inside their star's habitable zone. There are roughly 2,000 stars at a distance of up to 50 light-years from the Solar System [4] (64 of them are yellow-orange "G" stars like the Sun [5]). As many as 15% of them could have Earth-sized planets in the habitable ...
This is a list of unconfirmed exoplanets discovered or detected by the NASA Kepler mission (Kepler Candidates from the NASA Exoplanet Archive) that are potentially habitable. [1] [2] Those already confirmed are listed by their Kepler names in the list of potentially habitable exoplanets, and the data may differ when the planets are confirmed ...
The findings could help researchers better understand the factors that make exoplanets potentially habitable. The observations may also shed light on how our own solar system evolved.
The super-Earth exoplanet, known as TOI-715b, orbits a red dwarf star that is cooler and smaller than our sun. ... The habitable zone is usually calculated based on factors such as the size ...
The James Webb Space Telescope investigated a giant planet, K2-18b, that could be an ocean world, according to NASA. The exoplanet lies 120 light-years away from Earth.
Despite this, some scientists estimate that there are as many habitable exomoons as habitable exoplanets. [ 10 ] [ 11 ] Given the general planet-to-satellite(s) mass ratio of 10,000, gas giants in the habitable zone are thought to be the best candidates to harbour Earth-like moons.
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
