Two Earths?

Slate's blog Bad Astronomy reports that the Kepler spacecraft has detected at least five planets orbiting the cool orange star Kepler-62, with two Earth-sized and orbiting its habitable zone.

Assuming they’re made up of the same materials as Earth (metal and rock) and therefore have about the same density, you’d weigh 60 percent more on Kepler-62e, and 40 percent more on Kepler-62f. I’ll note that all things considered, neither would be paradise: Kepler-62e gets about 20 percent more sunlight than we do on Earth, and Kepler-62f gets about half; a bit hot and cold for my taste. But again, we don’t know the conditions on these planets. Give Kepler-62e a thin atmosphere, and Kepler-62f a thick one, and they might look a lot like Earth.
