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.

The discovery of a planet that is just 20 light-years away has been said to be the closest Earth analogue that scientists have ever uncovered.

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

Thirty years after the discovery of the first exoplanet, astronomers have detected more than 7,000 of them in our galaxy. But there are still billions more to be discovered. At the same time, exoplanetologists have begun to take an interest in their characteristics,

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,
