Since Kepler's laws of motion dictate that celestial bodies orbit more slowly when farther from the sun, we are now moving at ...

While overall Kepler-725c receives 1.4 times as much heat from its star as Earth does from the sun, this is just the average over the course of its orbit, and at times it is receiving less.

But the star, Kepler 62, is only about two-thirds as large as the Sun, and significantly dimmer, so a planet can approach much closer and still be hospitable.
