Is there life on Gliese 667Cc?

Is there life on Gliese 667Cc?

Gliese 667Cc is located in the habitable zone of its host star and is currently the most Earth-like planet known (ESI=0.82). The planet GJ667Cc is even more similar to our Earth than Kepler-22b, which was confirmed as a potentially habitable planet just a few weeks ago.

What are Earth-like planets called?

Size

Name Earth masses ( M ⊕) Note
Earth 1 Orbits in habitable zone.
Venus 0.815 Much hotter.
Kepler-20e < 3.08 Too hot to be Earth-like.
Proxima b >1.27 Closest exoplanet to Earth.

How far away is Gliese 667 Cc?

22.18 light years
Gliese 667 Cc/Distance to Earth

How big is the planet Gliese 667Cc compared to the Sun?

Gliese 667Cc is a Super Earth exoplanet 22 light years from Earth. The planet orbits around Gliese 667C, a small red dwarf star with a mass 31% of that of the sun.

Is the star Gliese 667C A M dwarf?

It is also believed that most of the stars that host exoplanets are M-dwarfs. The star Gliese 667C is also much cooler as compared to our Sun, the star has a surface temperature of about 3400°C.

What kind of radiation does Gliese 667 Cc receive?

When talking about radiation flux Gliese 667 Cc receives almost 90% of what we receive here on Earth (less solar radiation will also result in a lesser amount of disease caused by solar radiation). Most of the radiation is in Infrared, therefore it is very much possible that water can be present on the planet surface.

Is there liquid water on the surface of Gliese 667Cc?

GJ667Cc receives a radiation flux which is about 90% of what we receive from our Sun on Earth. Although most of this radiation is emitted in the infrared (IR), it is most likely enough to allow for liquid water on the planetary surface. The exact surface temperature is nevertheless uncertain and depends on a number of yet unknown factors.
