The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A , which is also the brightest star in Earth's night sky ; its white dwarf companion Sirius B is the hottest object among them.
Proxima Centauri is the nearest star to Earth after the Sun, located 4.25 light-years away in the southern constellation of Centaurus. This object was discovered in 1915 by Robert Innes. It is a small, low-mass star, too faint to be seen with the naked eye, with an apparent magnitude of 11.13. Its Latin name
An alternative name found in European sources, Toliman, is an approximation of the Arabic الظليمان aẓ-Ẓalīmān (in older transcription, aṭ-Ṭhalīmān), meaning 'the (two male) Ostriches', an appellation Zakariya al-Qazwini had applied to the pair of stars Lambda and Mu Sagittarii; it was often not clear on old star maps which ...
A new world is revealed day after day.” ... Proxima Centauri, the star referenced in Klein’s tweet, is the closest star to Earth, according to NASA. It is part of the Centaurus constellation ...
Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O. It may be later expanded to other types, such as S, D or C. The Alpha Centauri star system is the closest star system to the Sun.
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 ...
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]
