Kepler-69c has gone through a similar process; though initially estimated to be potentially habitable, [67] it was quickly realized that the planet is more likely to be similar to Venus, [68] and is thus no longer considered habitable. [1] Several other planets, such as Gliese 180 b, also appear to be examples of planets once considered ...
The nearest such planet was then as close as 12 light-years away [7] [8] but (see below) is now estimated slightly above four light-years away. On August 24, 2016, astronomers announced the discovery of a rocky planet in the habitable zone of Proxima Centauri, the closest star to Earth (not counting the
Proxima Centauri b is the closest exoplanet to Earth, [19] at a distance of about 4.2 ly (1.3 parsecs). [4] It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 AU, [1] over 20 times closer to Proxima Centauri than Earth is to the Sun. [20] As of 2021, it is unclear whether it has an eccentricity [e] [23] but Proxima Centauri b is unlikely to have any obliquity. [24]
The planet, dubbed Proxima b because it orbits Proxima Centauri, is thought to be a rocky and slightly more massive than Earth -- but that's not all. Scientists discover Earth-like planet orbiting ...
The first report of an exoplanet within this range was in 1998 for a planet orbiting around Gliese 876 (15.3 light-years (ly) away), and the latest as of 2024 is one around Struve 2398 A (11.5 ly). The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away
Proxima Centauri, the closest star to the Solar System, has three planets (b, c and d). The nearest system with four or more confirmed planets is Gliese 876 , with four known. [ citation needed ] [ a ] The farthest confirmed multiplanetary system is OGLE-2012-BLG-0026L , at 13,300 light-years (4,100 pc) away.
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.
Wolf 1061 c is an exoplanet orbiting within the habitable zone of the red dwarf star Wolf 1061 in the constellation Ophiuchus, about 14.1 light-years from Earth.At the time of discovery, it was the closest known potentially habitable exoplanet to Earth, though several closer ones have since been found.
