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,

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

Astronomers who identified HD 20794 d say its proximity to its host star and orbital pattern suggest it could hold water.

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,

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.

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.

Astronomers have officially confirmed the existence of HD 20794 d, a super-Earth located just 20 light-years away, with conditions that could make it one of the most promising exoplanets for life beyond our solar system.
