HD 20794d orbits its star with two other super-Earth planets, designated b and c, which orbit their star every 18.3 and 89.6 days, respectively. These were discovered in 2011 by a team of Geneva ...

But HD 20794d doesn't quite circle after all, because its orbit is an oval. This isn't unusual—most planets' orbits are sort of egg-shaped, or "eccentric"—but HD 20794d's eccentricity is ...

HD 20794 d does not transit its star, making atmospheric characterization challenging. However, future advancements in adaptive optics and next-generation telescopes could provide new insights despite ...

HD 20794 d orbits its star at a distance slightly less than Mars’s orbit around the Sun. For a star like the Sun, the habitable zone stretches from about 0.7 to 1.5 astronomical units, with Earth ...

Scientists say they may have discovered an exoplanet capable of supporting life. The planet, a super-Earth named HD 20794 d, is located just 20 light-years away.

Scientists found an intriguing world in our galaxy. They confirmed the existence of a rocky planet, called a "super-Earth," that's some six times as massive as Earth.While the world HD 20794 d is ...

However, HD 20794 d follows an elliptical, rather than circular, orbit, meaning its distance from its star varies. This makes it difficult to definitively determine its life-supporting potential ...

Dubbed HD 20794 d, this cosmic body is reportedly six times the size of Earth, hence its nickname “super-Earth.” It orbits a G-star similar to the sun, which it takes 647 days to ...

HD 20794d has a mass 6.6 times greater than Earth and was found by astronomers using the ESPRESSO and HARPS spectrographs on the European Southern Observatory's telescopes in Chile. These ...

That planet is called HD 20794d, and its mass is 6.6 times greater than Earth's. Its name indicates that it's the fourth planet to have been discovered orbiting HD 20794, ...
