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. WebbThe smallest solar system body to be classified as a dwarf planet by the International Astronomical Union (IAU) is Ceres, a 939.4-km-wide (583.71-mile) body located in the …

When Ceres was first discovered orbiting within the asteroid belt between Mars and Jupiter in … 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.
