Inaccuracies of these measured parameters make determining the true minimum distances of any encountering stars or brown dwarfs fairly difficult. [73] One of the first stars known to approach the Sun particularly close is Gliese 710. The star, whose mass is roughly half that of the Sun, is currently 62 light-years from the Solar System.
The most luminous known star. Quyllur: 2.1878 [5] 5,540 2023 First red supergiant at cosmological distances. Mothra: 2.091 [6] 5,400 2023 A binary consisting of a yellow supergiant and a B-type star. MACS J1149 Lensed Star 1: 1.49 [7] 4,410 2018 The most distant known star prior to the discovery of Earendel. SDSS J1229+1122: 0.000127 17 2013
It is the 2nd/3rd nearest individual star to the Solar System, and the fourth-brightest individual star in the night sky. Has one candidate exoplanet. Tau Ceti: 11.912 ± 0.007: G8V [74] 0.793 ± 0.004 [118] 0.783 ± 0.012 [118] 3.5 [118] 5.68 [118] Also the 20nd nearest star system to the Solar System. Has one confirmed exoplanet. Eta ...
This number is wrong; originally announced in 1891, the figure was corrected in 1910 to 40 ly (60 mas). From 1891 to 1910, it had been thought this was the star with the smallest known parallax, hence the most distant star whose distance was known. Prior to 1891, Arcturus had previously been recorded of having a parallax of 127 mas.
A star-forming region in the Large Magellanic Cloud. A star is a luminous spheroid of plasma held together by self-gravity. [ 1] The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night; their immense distances from Earth make them appear as fixed points of light.
Stellar parallax is most often measured using annual parallax, defined as the difference in position of a star as seen from Earth and Sun, i.e. the angle subtended at a star by the mean radius of Earth's orbit around the Sun. The parsec (3.26 light-years) is defined as the distance for which the annual parallax is 1 arcsecond.
Sirius is a binary star system consisting of two white stars orbiting each other with a separation of about 20 AU [e] (roughly the distance between the Sun and Uranus) and a period of 50.1 years. The brighter component, termed Sirius A, is a main-sequence star of spectral type early A , with an estimated surface temperature of 9,940 K . [ 14 ]
SIMBAD. data. ARICNS. data. Proxima Centauri is a small, low-mass star located 4.2465 light-years (1.3020 pc) away from the Sun in the southern constellation of Centaurus. Its Latin name means the 'nearest [star] of Centaurus'. It was discovered in 1915 by Robert Innes and is the nearest-known star to the Sun.
