The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [4] It is currently predicted to pass 0.1696 ± 0.0065 ly (10 635 ± 500 au) from the Sun in 1.290 ± 0.04 million years from the present, close enough to significantly disturb the Solar System's Oort ...
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 means the 'nearest [star] of Centaurus'.
The estimated time until the red dwarf star Proxima Centauri, the closest star to the Sun today, at a distance of 4.25 light-years, leaves the main sequence and becomes a white dwarf. [143] 10 13 (10 trillion) The estimated time of peak habitability in the universe, unless habitability around low-mass stars is suppressed. [144] 1.2×10 13 (12 ...
This year, Earth will be furthest from the sun on July 4. That moment, called aphelion, will occur when the distance between the two celestial bodies stretches to more than 94.5 million miles.
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.
Proxima Centauri is the closest star to the Sun at 4.2465 light-years (1.3020 pc). α Centauri A and B are Sun-like stars (class G and K, respectively) that together form the binary star system α Centauri AB. To the naked eye, these two main components appear to be a single star with an apparent magnitude of −0.27.
