This positively brilliant image is an artist’s impression of a sunset on Gliese 667 Cc, a super-Earth located 22.1 light-years from Earth (the one you’re on). In my opinion, this image is incredible, even though I’m not standing on the surface of this planet, the realism just washes over me.
This star system, called Gliese 667, is a trinary system. The two brightest stars in the system (which appear as the two smaller stars in the picture – I’ll explain why in a second) are Gliese 667 A and Gliese 667 B. Both of these stars are K-type main-sequence stars and are about 70% the mass of the Sun. They orbit each other at a distance of about 12.6 AU with an orbital period of about 42.15 years.
Gliese 667 C is the star that hosts our super-Earth friend depicted here. It is a red dwarf and orbits around Glieses 667 A and B. This star hosts two planets, Gliese 667 Cb and the one pictured here, Gliese 667 Cc. The planet has a mass of about 4.54 Earth masses and is right in the middle of the habitable zone.
Now, look at that picture one more time simply because it is awesome.
