Can humans live on Kepler-22b?
Can humans live on Kepler-22b?
Dubbed the “Goldilocks zone”, this is the orbital band where temperatures are just right to allow the existence of surface liquid water. This means the planet could have continents and oceans just like the Earth. Scientists believe Kepler-22b may not only be habitable, but possibly even inhabited.
What does Kepler-22b look like?
Kepler-22b orbits a star that is broadly similar to our own Sun. It’s a G-class yellow dwarf star, like the Sun, but it’s a little smaller, fainter and older. The star is about 600 lightyears away, in the direction of the constellation of Cygnus, and it’s not very bright as seen from the Earth (11th magnitude).
How far is Gliese 581g from its sun?
20.22 light years
Gliese 581/Distance to Earth
Is Gliese an exoplanet?
Gliese 581c is a super-Earth planet that was discovered in 2007. It resides in the Gliese 581 system, which at 20 light-years from Earth is relatively close to our planet (in celestial terms).
How long is a year on Kepler-22b?
290 days
Kepler-22b/Orbital period
Is Kepler-22b solid?
The surface temperature on Kepler-22b is estimated to be around 22°C. Water could thus theoretically exist in liquid form on the planet’s surface. Currently, it is not even clear if the planet is a rocky body with a solid surface like our Earth. It may also be a gaseous planet like Neptune, which would be inhabitable.
Where is Kepler-22b located?
constellation of Cygnus
Kepler-22b is located 620 light years away in the constellation of Cygnus. It has an orbital period of 290 days. Kepler-22b was the first of the Kepler planets to be found in the habitable zone of its host star. The habitable zone is the region in which liquid water could exist on a planet’s surface.
Does Kepler-22b have a moon?
Looks pretty bleak, science fiction fans. But hold on, there is some hope still for Kepler-22b. Earth, after all, has a moon, one about one-fourth as wide as our planet.
