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

It is believed that the planet, named HD 20794 d, is at just the right distance from its star to sustain water on its surface, but because this distance changes over the course of its elliptical rather than circular orbit it is too early to say whether it could host life.

An exoplanet is a planet outside our solar system that usually orbits a star in our galaxy. More than 7,000 have been found in the Milky Way since the first confirmed discovery in the 1990s, and "billions more remain to be discovered", said Tech Explorist.

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

Well, we could be closer to discovering whether there really is alien life out there after researchers discovered a new 'super-Earth' which is six times bigger than our planet and may well inhabit extraterrestrials.

Earth,” dubbed HD 20794 d, boasts a mass six times that of our planet and resides within the star’s “habitable zone.” The zone represents the optimal distanc

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.
