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 located in a star system less than 20 light-years away, making it one of the closest candidates for further research.

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

Earth" planet that may have conditions suitable for life, according to the University of Oxford. The exoplanet—a planet outside our solar system—has a mass six times greater than that of Earth and orbits in the "habitable zone" of a nearby star similar to our sun,

Astronomers have discovered another exoplanet that may have favourable conditions for the existence of liquid water. We are talking about HD 20794 d – a planet belonging to the group of so-called super-Earths.

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.

Located less than 20 light years away, HD 20794d could potentially be one of the most Earth-like planets found so far, despite its extreme climatic variability.

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.
