Astronomers Discover More Than 100 Exoplanets With NASA Kepler Space Telescope

Only two of the planets have potential for surface water to exist.

Though two of the planets "are too hot to support life as we know it," two other planets in this system -- K2-72c and K2-72e -- are in the star's "habitable" zone, NASA said. This means that liquid water could exist on these planets' surfaces.

The only problem is K2-72c and K2-72 circle so close to their star that their orbits are even tighter than that of Mercury's around the sun, and Mercury is the closest planet to our sun.

Despite this fact, the possibility that life could arise cannot be ruled out, according to Ian Crossfield, a Sagan Fellow at the University of Arizona's Lunar and Planetary Laboratory in Tucson.
