NASA scientists believe they are a step closer to finding Earth-like planets, following the discovery of the new planet Kepler-22b.
The space agency said that the new planet has many similarities to planet Earth and that there is the possibility that water exists on Kepler-22b's surface. This is because the planet was found in the habitable zone and was orbiting a star that's similar to the Earth's sun.
Here are five facts about Kepler-22b (based on released information from NASA):
1. Kepler-22b is the first potentially habitable world confirmed beyond our solar system.
2. The planet is about 2.4 times the radius of Earth. Scientists still don't know if Kepler-22b is solid or gaseous.
3. Kepler-22b is located 600 light-years away.
4. The planet, though larger than Earth, has an orbit of 290 days around a sun-like star resembling that of Earth.
5. The planet's host star is slightly smaller and cooler, but it belongs to the same class as our sun (a G-type star).
