Proxima Centauri

It is a world similar to earth with water containing carbonaceous products rich in diamond, graphite and iron core and maybe comparatively lesser plate tectonic activity. It has a companion star Alpha Centauri B (Toliman). Proxima centauri is an outlier in a three star system. Binary companion Alpha Cenatauri A and Alpha Centarui B, orbit their mutual center of gravity every 80 years.

Barnard's Star

6 light year's away, a red dwarf star, is famous for it's fastest speed of locomotion. It is the fastest star in the sky. 

Wolf 359

A star in wolf's clotthing. A red dwarf, one of the smallest stars, similar in diameter to Jupiter than to sun. 

Brightest Star

Sirius A, the brightest star in the sky, has a luminosity 25 times brighter than that of Sun. The light shone glows blue-white. With surface temperature 17,400F (9,600 C), diameter 70 percent wider than Sun's diameter and with double mass, this is one of the rarest stars in the sky.
