This artist's concept depicts one possible appearance of the planet Kepler-452b, the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. The habitable ...

It's thus in a more energetic phase of its life cycle than the sun is; indeed, the star is about 10 percent larger and 20 percent brighter than Earth's sun. (That means the sunlight on Kepler-452b ...

The planet, called Kepler-452b, is about 60% larger in diameter than Earth and circles a sun-like star that sits about 1,400 light-years away in the constellation Cygnus.

The planet, known as Kepler-452b, orbits a yellow G2-type star some 1,400 light years away in the constellation Cygnus, taking 385 days to complete one trip around its sun.

Kepler-452b orbits its star at a distance just 5 percent more than Earth orbits the Sun, with a year 385 days long. While the star is similar to the Sun, it’s older, and stars brighten as they age.

Because Kepler 452b orbits at an Earth-like distance from a sun-like star, the amount of sunshine it gets is expected to be similar to that on Earth, said Jenkins. "It would feel a lot like home ...

Scientists announced Thursday the discovery of Kepler-452b, shown here in an artist's rendering. It's being called Earth 2.0 because it shares so many similarities with our planet. NASA Ames/JPL ...

Kepler-452b is 1,400 light-years away in the constellation Cygnus. Kepler-452b is the first world to be discovered that is about Earth's size, orbits a star similar to our sun and occupies the ...

A year on Kepler-452b, which is about 1,400 light years from us in the constellation Cygnus, is 385 days, meaning its orbit is just a bit farther away from its star than the Earth is from the sun.

Kepler-452b's star is apparently older than the sun — 6 billion years, compared to 4.5 billion years. It's thus in a more energetic phase of its life cycle than the sun is; indeed, the star is ...
