Most “Earth-Like” Planets Ever Discovered

An Artist’s Impression of What the Exoplanets May Possibly Look Like

Eight new Earth-like exoplanets have been discovered, including two that are the most similar exoplanets to Earth ever found.  All eight are found in a “Goldilocks Zone”, where the temperature is just right to support life. The two most similar to Earth, Kepler-438b and Kepler-442b, both orbit red dwarf stars smaller than the Sun.

The discovery of the eight exoplanets doubles the number of planets thought to be in a “Goldilocks Zone” with their parent stars. Kepler-438b, which is barely larger than Earth, is the more likely of the two to support life, with scientists calculating it has a 70% chance of being rocky.
