A Super-Earth or super-terran or super-tellurian is a type of exoplanet with a mass higher than Earth, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17.1 times Earth's, respectively. [1]

Jan 28, 2025 · A super-Earth planet that dips in and out of its star's habitable zone has been discovered just 19.7 light-years away.

Oct 28, 2024 · The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth — a so-called super-Earth. Data from a worldwide array of telescopes, including ESO’s planet-hunting HARPS instrument, have revealed this frozen, dimly lit world.

Jan 29, 2025 · Exoplanet HD 20794 d offers a revealing case study of a super-Earth occupying a shifting seat at the edge of its star’s habitable zone. The research expands the horizon of exoplanetary science, reinforcing the notion that the universe may contain abundant worlds capable of supporting life.

Jan 31, 2024 · The recently discovered super-Earth, TOI-715 b, might be making its appearance at just the right time. Its parent star is a red dwarf, smaller and cooler than our Sun; a number of such stars are known to host small, rocky worlds. At the moment, they’re the best bet for finding habitable planets.

Scientists have discovered a super-Earth, named TOI-715 b, located within the “conservative” habitable zone of a nearby red dwarf star. This revelation has ignited the astronomical community with the potential of uncovering conditions that are suitable for life a …

Oct 4, 2022 · The discovery: LP 890-9 c, a “super-Earth” in the habitable zone of its star. Key facts: The planet, likely rocky but 40% larger than Earth, came to light during follow-up observations of its sister planet, LP 890-9 b.

super-Earth, type of planet that is between about 2 to 10 times the mass of Earth. Some astronomers use a size criterion to define super-Earths as being planets with a radius slightly larger than that of Earth but less than that of Neptune (about 4 Earth radii).

Jan 28, 2025 · HD 20794 d is categorized as a Super-Earth, meaning it is a rocky planet larger than Earth but smaller than gas giants like Neptune. What makes it especially fascinating is its highly elliptical orbit around a G-type star (similar to our Sun) located just 19.7 light-years away—an astronomical “close neighbour.”

Jan 28, 2025 · The exoplanet HD 20794 d, a super-Earth, has been discovered orbiting a G-type star 19.7 light-years away. It follows an eccentric orbit, oscillating in and out of the star's habitable zone,...
