Astronomers Puzzled By Discovery Of Unusual Ring System in Solar System
Publicado em 12 fevereiro 2023A ring system recently discovered by astronomers calls into question the current theories of how ring systems are formed, as it orbits much further out than is typical for other ring systems. The planetary ring was observed on the edge of the Solar System, around the dwarf planet Quaoar, which is approximately half the size of Pluto and orbits the Sun beyond Neptune. The study involved 59 academics from all over the world, led by the Federal University of Rio de Janeiro in [...]ver notícia
