Kepler-22 b

Kepler-22b is a fascinating exoplanet that orbits a Sun-like star within its habitable zone. This means that the planet is at just the right distance from its star for liquid water to exist on its surface.  

Key facts about Kepler-22b:

• Size: It's about 2.4 times larger than Earth.  

• Orbit: It orbits its star in about 290 Earth days.  

• Temperature: Its average surface temperature is estimated to be around 72 degrees Fahrenheit (22 degrees Celsius), which is similar to Earth's average temperature.  

While Kepler-22b is a promising candidate for a potentially habitable world, scientists aren't sure if it might have liquid water or not?

It could be a rocky planet with a deep ocean, or it could be a mostly water world or it couldn't be an ocean planet at all, it could just be a volcanic rocky planet.
