Kepler-22b is located 600 light-years away. While the planet is larger than Earth, its orbit of 290 days around a sun-like star resembles that of our world. The planet’s host star belongs to the same class as our sun, called G-type, although it is slightly smaller and cooler.

What would Kepler-22b look like?
Kepler-22b is located 600 light-years away. While the planet is larger than Earth, its orbit of 290 days around a sun-like star resembles that of our world. The planet’s host star belongs to the same class as our sun, called G-type, although it is slightly smaller and cooler.
Are there living things on Kepler-22b?
And where there is liquid water, there could also be life. Scientists believe Kepler-22b may not only be habitable, but possibly even inhabited.
Can you see Kepler-22b?
It was discovered by NASA’s Kepler Space Telescope in December 2011 and was the first known transiting planet to orbit within the habitable zone of a Sun-like star, where liquid water could exist on the planet’s surface. Kepler-22 is too dim to be seen with the naked eye.
Is Kepler-22b in our galaxy?
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.
What color is Kepler-22b?
Visual Facts

Why is Kepler-22b green?
The green area represents the habitable zone where water can exist in liquid form. Kepler-22’s star is a bit smaller than our sun, so its habitable zone is slightly closer in.
Does Kepler-22b have moons?
That said, a search for an exomoon around Kepler-22b (published in the Astrophysical Journal in 2013) found no evidence of any moon in that system.
Does Kepler-22b have gravity?
The gravity of Kepler-22b is uncertain, but likely to be higher than Earth’s gravity, which could pose a problem for settlement. Kepler-22b has 2.4 times the diameter of Earth, which would result in 2.4 times the gravity if its composition is also similar to Earth’s.
