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 ...
It is the 2nd/3rd nearest individual star to the Solar System, and the fourth-brightest individual star in the night sky. Tau Ceti: 11.912 ± 0.007: G8V [76] 0.793 ± 0.004 [120] [121] 0.800 ± 0.008 [121] 3.5 [120] 5.68 [120] Also the 20nd nearest star system to the Solar System. Eta Cassiopeiae A (Achird) 19.42 [12] G0V [122] 1.0386 ± 0.0038 ...
Alpha Centauri (α Centauri, α Cen, or Alpha Cen) is a triple star system in the southern constellation of Centaurus. It consists of three stars: Rigil Kentaurus (α Centauri A), Toliman (α Centauri B), and Proxima Centauri (α Centauri C). [14] Proxima Centauri is the closest star to the Sun at 4.2465 light-years (1.3020 pc).
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
Barnard's Star is a small red dwarf star in the constellation of Ophiuchus.At a distance of 5.96 light-years (1.83 pc) from Earth, it is the fourth-nearest-known individual star to the Sun after the three components of the Alpha Centauri system, and is the closest star in the northern celestial hemisphere.

Voyager 2 is not headed toward any particular star, although in roughly 42,000 years, it will pass the star Ross 248 at a distance of 1.7 light-years. [ 21 ] The closest stellar neighbors to Ross 248 are the binary systems Groombridge 34 , at 1.8 light-years away, and Kruger 60 , at 4.5 light-years.
It is the least massive and innermost known planet of the Proxima Centauri system. It is the least massive exoplanet detected with the radial velocity method as of 2022 [update] . Its proximity to the star and short orbital period of 5.1 days suggest that it is likely tidally locked due to strong tidal forces.
The nearest white giant. Capella A 42.919 ± 0.049 [9] G8III [9] 11.98 ± 0.57 [9] 2.569 ± 0.007 [9] 0.03 [10] The nearest yellow giant, together with Capella A. With a magnitude of 0.08, [11] the Capella star system is the 6th-brightest star in the night sky. Capella B G0III [9] 8.83 ± 0.33 [9] 2.483 ± 0.007 [9] 0.16 [10] The nearest yellow ...
