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. It has similar characteristics to Proxima Centauri b and is one of the nearest discovered potentially habitable exoplanets to Earth.
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 b is the closest exoplanet to Earth, [20] at a distance of about 4.2 ly (1.3 parsecs). [5] 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. [21] As of 2021, it is unclear whether it has an eccentricity [e] [24] but Proxima Centauri b is unlikely to have any obliquity. [25]
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 ...
Such a planet would lie within the habitable zone of Proxima Centauri, about 0.023–0.054 AU (3.4–8.1 million km) from the star, and would have an orbital period of 3.6–14 days. [85] A planet orbiting within this zone may experience tidal locking to the star. If the orbital eccentricity of this hypothetical planet were low, Proxima ...
Kepler-69c has gone through a similar process; though initially estimated to be potentially habitable, [66] it was quickly realized that the planet is more likely to be similar to Venus, [67] 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 ...
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
Sep. 26—Jupiter is closer to the Earth than it has been since 1963, meaning the solar system's largest planet will be exceptionally bright in the sky tonight. Every 13 months, the planet reaches ...
