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 small red dwarf Ross 248 will pass within 3.024 light-years of Earth, becoming the closest star to the Sun. [31] It will recede after about 8,000 years, making first Alpha Centauri (again) and then Gliese 445 the nearest stars [31] (see timeline). 50,000
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.

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.

The distance of Alpha Centauri from the Earth is now reckoned at 4.396 light-years or 4.159 × 10 13 km.) α Centauri A (left) is of the same stellar type G2 as the Sun, while α Centauri B (right) is a K1-type star. [67] Later, John Herschel made the first micrometrical observations in 1834. [68]
