HD 20794 d orbits a G-type star similar to the Sun and takes 647 days to complete one orbit—40 days fewer than Mars. The planet has a mass 6.6 times greater than Earth, making it easier to study ...

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 ...

The confirmation of HD 20794 d’s existence marks a major milestone in exoplanet research. For years, astronomers have suspected that this world might be hiding within the HD 20794 system, a star ...

The backdrop for one team is the discovery of super-Earth HD 20794 d, an exoplanet detected by researchers from the University of Geneva (UNIGE) and NCCR PlanetS. Orbiting in an eccentric path, HD ...

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 ...

Dubbed HD 20794 d (because HD 20794 is the name of its star and it is accompanied by two previously announced planetary siblings, HD 20794 b and HD 20794 c), this planet is at least as massive as ...

However, HD 20794 d makes up for that by being just 20 light-years away. That’s 40 percent of the distance to LHS 1140 b, and half the distance to TRAPPIST-1.

Named HD 20794 D, the newly discovered exoplanet orbits a star similar to the Sun, and researchers believe it may be able to sustain liquid water, which is vital for life, as we know it, to exist.

Dr Cretignier and colleagues know HD 20794 d has a mass six times that of Earth, but as yet they do not know the diameter. 'The method we are using only provides the distance to the star (the ...

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 ...

The planet, a super-Earth named HD 20794 d, is located just 20 light-years away. It has a mass six times that of our own planet and orbits within the habitable zone of its star.

Oxford researcher discovers new super-Earth HD 20794 d just 19.7 light-years away Researchers hail HD 20794 d as an 'invaluable test case' for detecting signs of life. A super-earth planet.
