Why do planetary rings have gaps? Why won t the rings break further?

The rings of the planet mainly revolve around the planet under the gravitational pull of the planetBut the interaction between the matter in the ring, the gravitational interaction between the ring and the planet's moons, causes structures to appear on the ring.

Saturn's rings, the dark bands between the A and B rings areCassini sewn。It is easy to send it downThe halo is actually made up of a series of finer halos and dark bands. Cassini is not empty in the seams, and there are dull rings.

Among the planets of the solar system, the most obvious ring is Saturn. Saturn's rings do not contain very much matter, and the total weight is estimated to be around 10 19 kg. The rings are very, very thin.

For example, the total width of the A-ring exceeds the diameter of the earth, but the thickness is only a few tens of meters. The origin of the rings may be moons that were disintegrated by Saturn's tides, but the exact origin is still debated.

From the point of view of modern astronomy, it is easy to solve Galileo's confusion. Mankind has long known that Galileo did not see Saturn's ears, but the "rings of Saturn" that everyone knows today. Both Saturn and Saturn's rings are in constant motion, and the angle of this thin ring relative to Earth's observers is changing.

Wider dark bands, such as Cassini's slits, are thought to be related to orbital resonance。At the location of the Cassini slit, a particle orbits Saturn, exactly half the size of Enceladus. In this way, the particles in Cassini's slit will be pulled by the gravitational pull of Enceladus in the same position for each revolution in orbit.

In this way, Saturn's rings are not really a "solid ring", just as the Milky Way is not a "river", and when it is not clear to see, people describe them as "rivers" or "rings". The first person to recognize that Saturn's rings are not a monolithic ring was Maxwell. At that time, Maxwell was still young, only in his twenties, and had not yet become the "father of electromagnetism".

He began studying Saturn's rings because of the difficulties with the "solid model of Saturn's rings", which had been recognized by most previous scientists. The motion of a uniformly rigid ring on the planet's edge is dynamically unstable, and any slight disturbance will cause the ring to fall apart and fall towards Saturn.

Although the dark ring between Cassini's slit and the thin ring is not hollow, there is a real "deep groove" in Saturn's rings (Figure 2). The appearance of these "real" annular cracks is thought to be related to the cleaning effect of small satellites in the ring. It will knock small particles along the way.

In 1991, one such small satellite was discovered in the Voyager data archivesIn 2005, the Cassini probe discovered another small moon in the Keeler Gap.

Saturn is known as the most beautiful planet in the solar system because it has a beautiful planetary ring, and if the Earth has planetary rings, then both from Earth and from outer space

Mission objects actually have intermolecular gaps.

It's because it has a beautiful planetary ring, if the Earth has a planetary ring.

If gravity is sustaining the motion of the halo matter, then the orbital radius of the gravel should be random, and we should see a smooth and continuous ring.

He's around the planet, so there must be gaps.

Planetary yellow seems to be made up of small galaxies.

This is due to the fact that the planet is too large.

There must be a gap in between.

This is because they don't interact with each other enough.

What you say does not correspond to the facts! All the objects on the planetary rings move in a uniform circular motion at almost the same speed, and they remain scattered only for various reasons (the biggest reason is that they cannot be stably maintained in the shape of a satellite below the Loch limit).

However,Planetary rings are not necessarily stable, but they are broken in time units of tens to billions of years, doesn't mean they won't break! The reason is similar to that satellites in geosynchronous orbits must eventually crash. Both Jupiter's rings and Uranus' rings have this tendency.

Saturn's rings have some peculiarities, with several rings also having a lifetime of up to 300 million years. But there are shepherd dog moons like Enceladus that can exist for a longer period of time, and some planetary rings can exist longer.

Because the qualitative change of the planetary ring may take hundreds of millions of years, or even longer, it can be assumed that the planetary ring will not break further.

According to Laplace, the halo is made up of a series of thin rings arranged together, which appear solid from the distance of the Earth, because they are arranged extremely closely.

If the orbital period of an asteroid is an integer ratio to the orbital period of Jupiter, it will be periodically disturbed by Jupiter, so that the orbit will be unstable, and eventually leave the orbit, so that the number of asteroids in the orbital radius will be very small, and it will be the same slit.

That's because it's facing us at different angles. When we happen to look from its side, the thin halo seems to disappear.

The gravitational interaction between the ring and the planet's moons causes structural gaps to appear in the ring.

Because some planets have multiple moons, and the gravitational pull of different moons on the rings is different.

The angle of the shot is different, and the gravitational pull between the planets is also different, so what we see is a gap.

The material of the planet is different, and from different angles, the closing line gives people a different vision, so you will see the gaps.

The halo seen at different angles is also different, and the refracted halo is also different.

As a result, the orbit is unstable, and it eventually leaves the orbit, so that the number of asteroids in the radius of this orbit will be very small, and it will be the same slit.

There are four large planets in the solar system that are surrounded by rings, which has attracted the attention of Chinese astronomers. Many people wonder if the other planets of the solar system, including the inhabited Earth, are all circumferential. In 1964, the former Soviet Union sent two artificial satellites into an elliptical orbit around the Earth, equipped with meteorite particle recorders.

The measurements show that there is also a stable, fairly dense ring of dust near Earth.

Further observation revealed that they were rings on the Earth's periphery with different inclinations from the equatorial plane, and were made up of extremely fine dust particles. The height of the dust ring ranges from kilometers to 4 million kilometers. As the distance away from the Earth's surface increases, the number of dust particles decreases significantly.

Scientists from various countries have different opinions on whether other terrestrial planets are circumferential, but they are all conjectures, and there is no reliable observational evidence to prove it. Perhaps as space exploration progresses, the universe will provide some new information, which is still a mystery that no one can solve.
