Proxima Centauri

Proxima Centauri is the nearest star to the sun and is at 4.2 lightyears. I choose this theme because I read about it in a Physics book written by a famous Physics teacher of MIT. It sounds really interesting to talk about stars and especially if it is the nearest star to the Sun. This star is classified as a red dwarf located in the constellation of Centauri. It was discovered in 1915 by Robert Innes, it has a diameter of 1/7 of that of the Sun and its density is 40 times bigger than the Sun.
