Several other planets, such as Gliese 180 b, also appear to be examples of planets once considered potentially habitable but later found to be interior to the habitable zone. [ 1 ] Similarly, Tau Ceti e and f were initially both considered potentially habitable, [ 70 ] but with improved models of the circumstellar habitable zone, as of 2022 PHL ...
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.
TOI-2257 b is an extremely eccentric (0.496) [2] exoplanet in or near the circumstellar habitable zone of the star TOI-2257, 188 light-years away. It is likely a sub-Neptune exoplanet, with a mass of 5.71 Mearth and a radius of 2.19 Rearth. [3]
In 2023, astronomers used the radial velocity method to confirm that the exoplanet Wolf 1069 b sits in the habitable zone of Wolf 1069. Located 31 light years from Earth, this planet is 1.26 times the mass of Earth and has a radius of 1.08 times the Earth's. Though Wolf 1069 b is likely tidally locked, its daylight side may still be habitable.
On May 10, 2016, NASA announced that the Kepler mission has verified 1,284 new planets. [20] Based on some of the planet's sizes, about 550 could potentially be rocky planets . Nine of these orbit in their stars' habitable zone .
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.
[15] [16] 11 billion of these estimated planets may be orbiting Sun-like stars. [17] The nearest such planet may be 12 light-years away, according to the scientists. [15] [16] As of June 2021, a total of 59 potentially habitable exoplanets have been found. [18]
This list of exoplanets discovered in 2021 is a list of confirmed exoplanets that were first observed in 2021. For exoplanets detected only by radial velocity , the listed value for mass is a lower limit.
