2.  It is smaller than the Sun.  It is “4.2 billion light years away” from Earth.  It is also is “18,000 times fainter than the sun.”

3.  It is a red dwarf that is the closest star to the sun.  Its “surface temperature is as low as 3300 K.”

4.  “It was discovered in 1915 by Robert Innes, the Director of the Union Observatory in South Africa.”

5.  “ Although it has a very low average luminosity, Proxima is a flare star that undergoes random dramatic increases in brightness because of magnetic activity.” `

6.  “The mixing of the fuel at Proxima Centauri's core through convection and the star's relatively low energy production rate suggest that it will remain a main-sequence star.

7.  Proxima is a “red dwarf Star,”

8.  Of the Sun with Supermassive Stars.

9.  Its estimated mass is equal to 129 Jupiters!  During solar flares, the flares can get the same size of the star!  Proxima Centauri is approximately “4.2 light years away from Earth.”

10.  “Proxima Centauri has been the closest star to the Sun for about 32,000 years.”  It is possible that there are habitted planets that orbit Proxima.  This planet(s), however, would “experience tidal locking.”

11.  You can also call Proxima Centauri Alpha Centauri C.  It “is part of a triple star system” and is smaller that both stars Alpha Centauri A and Alpha Centuari B.
