Kepler 452 b is estimated to be 1.6 times the size of our own
world, and resides
in a clement, life - friendly
orbit around a star
in the constellation of Cygnus some 1,400 light - years away that is eerily similar to our own
sun.
Early
in its mission, Kepler managed to find some tantalizing
worlds, a handful of supersize cousins of Earth, most of them
in clement
orbits around smaller, cooler, quieter stars than the
sun called M and K dwarfs, but all the setbacks made finding smaller Earth - sized planets
around sun - like G stars a very tall order.
