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

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.

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

But according to an international team of researchers, including some from the University of Geneva, in a study published Tuesday in Astronomy & Astrophysics believe the super-Earth, dubbed HD 20794 d, could offer new insights into what makes a planet capable of supporting life.

Astronomers have discovered another exoplanet that may have favourable conditions for the existence of liquid water. The planet in question is HD 20794 d, part of the group known as super-Earths. It is located in a star system less than 20 light-years away,
