You can't see it, but the latest Earth-like planet found by astronomers is out there in the night sky, within the feature known as the Summer Triangle.
The planet Kepler-452b is 1,400 light years away within the constellation Cygnus, the swan. It is about 6 billion years old, 1.5 billion years older than Earth, and 60 percent larger in diameter than our home planet, NASA officials announced Thursday. Its star, Kepler 452, is also older and bigger, as well as brighter than our sun.
Deneb, the brightest star within Cygnus, is one of three vertices of the Summer Triangle, which is out all night this time of year. The other two are Vega, of the constellation Lyra, and Altair, of the constellation Aquila.
The triangle appears in the east at nightfall, with Vega shining the brightest. All three stars are visible on a clear night even amid urban light pollution, according to EarthSky.org.
Vega and Altair are far closer to Earth than Kepler 452, both within 25 light years, while Deneb is estimated to be around the same distance as Kepler 452, and possibly much farther.
The three stars are all significantly brighter than Kepler 452. While Kepler 452 is about 20 percent brighter than our sun, Vega is 60 times brighter than our sun.
