Jan 23, 2025 · This exoplanetary encyclopedia — continuously updated, with more than 5,800 entries — combines interactive 3D models and detailed data on all confirmed exoplanets. When you select a planet’s name, see a visualization of each …

Jan 28, 2025 · The exoplanet’s size, proximity to Earth, and potential to hold water makes it a prime candidate to search for life, as well as testing hypothesis about conditions that could support it. New instruments, like the European Southern Observatory’s Extremely Large Telescope (ELT), will hasten that search when they come online. ...

Jan 30, 2025 · An exoplanet is any planet beyond our solar system. Most of them orbit other stars, but some free-floating exoplanets, called rogue planets, are untethered to any star. We’ve confirmed more than 5,800 exoplanets out of the billions that we believe exist.

An exoplanet was defined by the following criteria: Objects with true masses below the limiting mass for thermonuclear fusion of deuterium (currently calculated to be 13 Jupiter masses for objects of solar metallicity) that orbit stars or stellar remnants are "planets" (no matter how they formed). The minimum mass/size required for an ...

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, where ...

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.

Oct 29, 2024 · The planets beyond our solar system are called “exoplanets,” and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars.

Jan 31, 2024 · The discovery: A “super-Earth” ripe for further investigation orbits a small, reddish star that is, by astronomical standards, fairly close to us – only 137 light-years away. The same system also might harbor a second, Earth-sized planet.

Jan 11, 2023 · Researchers confirmed an exoplanet, a planet that orbits another star, using NASA’s James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter.

Jan 28, 2025 · I do not see radius reported. 6.6 earth mass exoplanet with 2.0 earth radii, mean density 4.53 g cm^-3. Surface gravity compared to Earth would be about 1.65 earth g. It likely has a dense atmosphere.
