A planetary ring is a ring of cosmic dust and other small particles orbiting around a in a flat disc-shaped region. The generally accepted theory is that ringed planets have sufficient gravity to attract and hold a lot of space debris that is left over from the matter that originally compressed to form the sun and its planetary system. It is also possible that the debris which we now see as rings was once part of a larger satellite(s) that was broken up either by collisions with other small bodies or by the constant gravitational stress exerted by the planet around which they circulate. The debris also tends to get flattened by the rotation, so we see it as rings many miles wide but less than a mile thick.

Which of the planets does NOT have rings around it?
All inner planets does not have rings around it.
What are the rings around planets called?
The rings around planets are called rings, or solar rings. Saturn is a planet that is most famous for having rings around it.
How many planets are in our solar system have rings?
Four the planets in the solar system have rings. They are the four giant gas planets Jupiter, Saturn, Uranus and Neptune. Saturn, which has by far the largest ring system, was know to have rings for a long time. It was not until the 1970's that rings were discovered around the other gas planets. The rings around Jupiter, Uranus and Neptune are much smaller, darker and fainter than the rings of Saturn.
Is it true Saturn is the only planet with rings of rock and ice around it?
No, other planets also have rings.
What are the group of planets called that do not have rings around them?
The inner planets, also known as rocky or terrestrial planets, do not have significant ring systems.
Which of the planets does NOT have rings around it?
All inner planets does not have rings around it.
What are the rings around planets called?
The rings around planets are called rings, or solar rings. Saturn is a planet that is most famous for having rings around it.
What are rings around the planets?
The rings around the planets are made of gas and rubbish as a result of pollution from Earth
Does planets have rings around it?
yes it has about 360000 thousand rings rotating around it
What planets do NOT have rings around them?
MercuryVenusEarthMarsVenus
Do dwarf planets have rings around it?
No
Do most planets have rings?
half; all the outer planets have rings not including dwarf planets (Jupiter has one thin ring around it).
What are the rings of the planets?
they are stuff around a planet
Which planets has rings around them?
Uranus and Saturn
Does earth has rings around it?
There are a few planets within our solar system that contain rings around them. However, the planet Earth is not one of those planets since the atmosphere is not right for rings.
If there are rings orbiting your planet describe the rings?
There are no rings around earth, or any of the rocky planets.
Why does some planets have rings round them?
Most rings are made of ice. Therefore the planets that are father away from the sun are colder than the ones near the sun. Ice will form rings around the planets.
