How are the rings of uranus oriented
Web21 de jun. de 2024 · Saturn's rings are largely water ice, and so they reflect more sunlight back to us. Jupiter's rings, have lower proportions of ice, and lots of smaller dust particles that tend to scatter light forward rather than back to us. The ring systems of Uranus and Neptune are made of really dark material, so also don't reflect much light in our direction. The rings of Uranus are intermediate in complexity between the more extensive set around Saturn and the simpler systems around Jupiter and Neptune.
