Saturn has two bright prominent rings plus a fainter third ring that can be seen from Earth. In addition, Saturn has several less prominent rings.
Saturn!
Mars has two prominent rings that are composed of primarily dust and rocks. These rings are relatively small compared to other planets' rings, such as those around Saturn.
Planet Mars has two moons, Phobos and Deimos, and has no rings as far as we know.
URANUS
Saturn is not the only planet that has a ring system, but it is by far the most prominent. Uranus has a system of five rings (here's a picture) and Jupiter also has two rings (here's another). However, while Saturn's rings are composed of dust particles, the rings around Uranus and Jupiter are primarily composed of an electromagnetic plasma (hot ionized gas!). There are several competing theories for the formation of Saturn's rings. The first is that Saturn's rings are a remnant left over from when the planet was formed. As gas and dust collapses to form a planet it forms a disk that orbits the young planet. Material in this disk gradually falls onto the planet or diffuses away. The rings could be what is left of that initial proto-planetary disk.
Perhaps this question is about "rings"? Saturn is known as the ringed planet, but Jupiter, Uranus and Neptune all have smaller rings.
Saturn has MORE than two but no other planet has just two. Jupiter has one and Uranus has one.
Uranus was known to have 11 rings, however the Hubble space telescope discovered two more bringing the total to 13.
Mars does not have any rings but possesses two moons named Deimos and Phobos .
No, the distance between two adjacent bright and dark rings in Newton's rings pattern is not equal. The spacing between the rings decreases as we move from the center outwards, due to the curvature of the lens. This pattern is a result of the varying film thickness of air between the lens and the flat glass plate.
The two humps observed by Galileo on the planet Saturn were later revealed to be the rings of Saturn when they were viewed through more powerful telescopes. Galileo did not have a clear view of the rings' true nature due to limitations in his equipment.
Mercury, Venus, Mars and Earth has no rings. All the inner planets don't. Although Pluto is a planet, it is too small to be considered a planet so it is a dwarf planet. But Pluto also have no rings.
