Webb11 feb. 2024 · Exoplanet Celebs. The closest star to our Sun, Proxima Centauri, is a red dwarf. This is why scientists got excited when they found an Earth-sized planet there known as Proxima b (in exoplanet naming, the “a” designation usually goes to the star) in 2016. Lying just 4.2 light years away from Earth, Proxima b sits in its star’s habitable ...

Webb15 dec. 2024 · A team led by researchers at the University of Montreal has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," where water makes up a large fraction of the entire planet. These worlds, located in a planetary system 218 light-years away in the constellation Lyra, are unlike any planet found in our solar system.

Beside directly orbiting the Sun, the qualifying feature of a dwarf planet is that it have "sufficient mass for its self-gravity to overcome rigid-body forces so that it assumes a hydrostatic equilibrium (nearly round) shape". Current observations are generally insufficient for a direct determination as to whether a body meets this definition. Often the only clues for trans-Neptunian objects (TNO) is a crud…
