The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Kepler-1638b was thought to be a possibly habitable planet with a radius smaller than 2 R 🜨 after the validation. However based on the later measurement of host star parallax by Gaia, the radius of the planet was revised upward to 3.226 +0.201 −0.315 R 🜨, resulting in it being a ice giant like Neptune with poor prospect for habitability ...
Planet type Circumbinary planet: Planet orbits a single star in a multiple star system Planet has a circumbinary orbit in a system with more than 2 stars Planet discovered by Kepler community Potentially habitable None of the above
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
On its discovery, the planet was designated PSR 1257+12 C and later PSR B1257+12 C. It was discovered before the convention that extrasolar planets receive designations consisting of the star's name followed by lowercase Roman letters starting from "b" was established. [12]
Planetary oceanography, also called astro-oceanography or exo-oceanography, [1] is the study of oceans on planets and moons other than Earth.Unlike other planetary sciences like astrobiology, astrochemistry, and planetary geology, it only began after the discovery of underground oceans in Saturn's moon Titan [2] and Jupiter's moon Europa.

The planet is located some 1,200 light-years away. A light-year is 5.8 trillion miles. It's the second-lightest exoplanet found so far based on its dimensions and mass, according to the researchers.
