Presentation transcript:

 It was discovered in 1915 by Robert Innes, who was director of Union Observatory in Johannesburg, South Africa.

The name Proxima comes from a Latin word meaning “nearest” or “next to” because it’s the third closest to the sun.

 Proxima Centarui is part of the triple star system and smaller than its partners Alpha Centarui A and Alpha Centarui B. its approx. one seventh the size of our sun.

 If we were nearer like on Venus’ orbit the heat would have evaporated all our oceans, but if we were father the temperature would be too cold to support life.

 Proxima Centarui’s flares are believed to be caused by a magnetic activity.

 Even though Proxima Centarui is nearest to the sun it is still 4.2 light years away!

 Proxima Centarui is smaller than our sun with a mass approx solar masses and a radius of only about solar radii.

 Proxima Centauri’s apparent magnitude is and the absolute magnitude 15.5 Sun Video
