Feb 1, 2025 · HD 20794 d is a super Earth exoplanet that orbits a G-type star. Its mass is 4.8 Earths, it takes 89.7 days to complete one orbit of its star, and is 0.3625 AU from its star. Its discovery was announced in 2011.

82 G. Eridani (HD 20794, Gliese 139, e Eridani) is a star 19.7 light-years (6.0 parsecs) away from Earth in the constellation Eridanus. It is a main-sequence star with a stellar classification of G6 V, and it hosts a system of three confirmed planets and a dust disk.

3 days ago · Astronomers have made a groundbreaking discovery: a super-Earth, HD 20794 d, located just 20 light-years away, could be one of the closest and most promising exoplanets for studying conditions suitable for life. This planet, orbiting a sun-like star, lies within the habitable zone, meaning it could potentially sustain liquid water on its surface—a key ingredient

Jan 29, 2025 · HD 20794 d in the habitable zone. A super-Earth is a planet that is larger than Earth but smaller than gas giants like Neptune. HD 20794 d occupies a system that includes two other planets, all revolving around a G-type star (similar to our Sun) at a distance of approximately 19.7 light-years.

Jan 30, 2025 · 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 ...

Feb 3, 2025 · 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 ...

Jan 28, 2025 · A team of researchers have confirmed an Earth-like planet named HD 20794 d, they report in the journal Astronomy and Astrophysics. The exoplanet is especially interesting to astronomers because at a mere 19.7 light-years away, it’s practically a neighbor.

Jan 29, 2025 · The latter is likely to be a rocky planet in the habitable zone of HD 20794. From the analysis of activity indicators, we find evidence of a magnetic cycle with a period around 3000 d, along with evidence pointing to a rotation period around 39 d. We have determined the presence of a system of three planets orbiting the solar-type star HD 20794.

Jan 29, 2025 · This is the background to the discovery of super-Earth HD 20794 d by an international team. The new planet lies in an eccentric orbit, so that it oscillates in and out of its star's habitable zone.

Jan 28, 2025 · This is the background to the discovery of super-Earth HD 20794 d by an international team including the University of Geneva (UNIGE) and the NCCR PlanetS. The new planet lies in an eccentric ...
