NASA said today that a new Earth-like planet was discovered using Kepler spacecraft. “Earth’s bigger, older cousin: the first nearly Earth-size planet to be found in the habitable zone of a star similar to our own.
But, the NASA said that it can’t confirm if the planet is rocky like ours or has water and air.
“Today, Earth is a little less lonely, ” Kepler researcher Jon Jenkins said. Chances are high that it can also host life.
According to the CNN, the planet named Kepler-452b is some 1,400 light years from Earth in the constellation Cygnus. It’s about 60% bigger than Earth, NASA says, and is located in its star’s habitable zone — the region where life-sustaining liquid water is possible on the surface of a planet.
A visitor there would experience gravity about twice that of Earth’s, and planetary scientists say the odds of it having a rocky surface are “better than even.”
While it’s a bit farther from its star than Earth is from the sun, its star is brighter, so the planet gets about the same amount of energy from its star as Earth does from the sun. And that sunlight would be very similar to Earth’s, Jenkins said.
If the assumptions of planetary geologists are correct, he said, Kepler-452b could have a thicker atmosphere than Earth’s, as well as active volcanoes.
