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.

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.

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

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

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.

Earth” planet that may have conditions suitable for life. The planet is outside our solar system and has a mass six times greater than that of Earth. The discovery is of an exoplanet, this is any planet beyond our solar system,
