Scientists have discovered a planet about five times bigger than Earth flying the right distance from its parent star for liquid water to exist on its surface, a condition believed to be necessary for life.
The newly found planet circles a star dimmer than the sun that is located 22 light-years away in the constellation Scorpius (also known as Scorpio.) It passes around its parent star in 28.15 days.
While far closer to its star than Earth is to the sun, the planet’s parent star, known as GJ 667C, is a small dwarf star that emits most of its light in infrared radiation. That means GJ 667C's so-called "habitable zone" -- the region where surface water can exist in liquid form -- is closer than our sun's region.
