This number is likely much higher, due to the sheer number of stars needed to be surveyed; a star approaching the Solar System 10 million years ago, moving at a typical Sun-relative 20–200 kilometers per second, would be 600–6,000 light-years from the Sun at present day, with millions of stars closer to the Sun. The closest encounter to the ...
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
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.

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 but is not visible to the naked eye because of ...
A celebrated French physicist named Étienne Klein tweeted out an image on July 31 claiming it showed Proxima Centauri, the nearest star to the sun.
At its nearest approach, α Centauri will attain a maximum apparent magnitude of −0.86, comparable to present-day magnitude of Canopus, but it will still not surpass that of Sirius, which will brighten incrementally over the next 60,000 years, and will continue to be the brightest star as seen from Earth (other than the Sun) for the next ...
