Description

Arcturus is the fourth brightest star in the night sky, and the brightest in the northern hemisphere. Located at a distance of 36.7 light-years from Earth, it is one of the most luminous stars in the Sun's nearby vicinity along with Vega and Sirius. Scientists believe that Arcturus may have exhausted its hydrogen fuel and started fusing helium. It will continue to expand before expelling its outer atmosphere and eventually ending its life as a white dwarf.
