HD 20794 d completes its orbit just shy of two Earth years, placing it well within reach of conditions that might harbor life.

UK researchers have confirmed the existence of a “super Earth” located 20 light-years away that could reveal the existence of extraterrestrial beings.

Found by Dr Michael Cretignier of the University of Oxford, the planet has a mass six times greater than Earth's and orbits in a "habitable zone" of a star similar to the sun.

Astronomers have found some pretty wild exoplanets. Some are balls of lava the temperature of hell, one is partially made of diamond, and another may rain molten iron. However, not all exoplanets are this extreme.

Named HD 20794 D, the newly discovered exoplanet orbits a star similar to the Sun, and researchers believe it may be able to sustain liquid water, which is vital for life, as we know it, to exist. "Best of all,

Earth” planet that may have conditions suitable for life. The planet is outside our solar system and has a mass six times greater than that of Earth. The discovery is of an exoplanet, this is any planet beyond our solar system,
