NASA discovers Earth-like planet

Kepler 452B, located 1400 light years away, is the most Earth-like planet found by NASA. It orbits a G star similar to our sun in the constellation Cygnus, with a year lasting 385 days. Kepler 452B is 5% farther from its sun than Earth is from ours, yet receives similar sunlight due to its sun being 10% larger. Gravity on Kepler 452B is about twice as strong as on Earth.

What is the significance of Kepler 452B receiving the same amount of sunshine as Earth?

How does the gravity on Kepler 452B compare to that on Earth?
