Why does earth have no rings?

Answer 1

Part of the answer to this question is: Timing.

Over the past 5 billion years since the formation of the planets, nearly all of them would have had rings at one time or another.

Rings do not last very long. Saturn's rings are probably only about 50-100 million years old, and in another 50-100 million years, they will be gone.

Jupiter probably once had a magnificent ring system, but it is nearly gone - all material has either fallen into Jupiter or scooped up by the nearest large moon, Io.

However, larger planets are much more likely to form rings than smaller planets.

The reason is that larger planets have a much larger Roche Limit. A Roche Limit is the closest that a moon can come before the gravitational tides from the planet tear the moon apart (and turn it into a ring).

Mars' larger moon, Phobos, is slowly spiraling into Mars. It is estimated that in another 50 million years or so, Mars' gravity will tear Phobos apart and Mars will for a short while have a ring system, which, like Saturn's, slowly fall down to the planet.

Earth's moon, however, is being pulled away from Earth by the Sun. On the other hand, if Humans stopped sending satellites up, most of the satellites in higher orbits would slowly line up with the Equator and form a unique, metallic ring system of derelict satellites. (All the lower satellites will simply fall back to the planet).

Answer 2

ring is nothing but group of thousands of mini satelites,in case of earth,she has only one big satelite i.e moon,in case if satan such a number of satelites are due to comets,orparts of x planet between jupitor and mars

Answer 3

Most of the really large planets have rings. Most of the small planets do not have a rings. A ring is formed when some debris near the planet cannot form into a moon, therefore it becomes a ring. The Earth and Mars have moons. Jupiter and Saturn have rings and moons. The Earth wasn't big enough, like Jupiter or Saturn to have a ring.

Answer 4

Probably the relative size of the moon;

if any tried to form the combined tidal forces (Earth's and the moon's) would break it up.

Answer 5

Becaus thats the moons of the planets how are have rings.

Answer 6

no earth dose not6 have any rings

Answer 7

nope it dose not xx
