There are eight planets in the solar system, why didn t they collide?

Because the eight planets all follow their own orbits, they do not interact with each other.

They all have their own gravitational pull, and they all revolve around the sun in an orderly manner.

The eight planets of the solar system all orbit the sun very regularly.

Their trajectories are different, and the space between them is actually quite large.

Because each planet orbits differently.

Because they're all in their own orbits.

Because each has its own running track.

Every planet their trajectory is different, they.

They all have their own tracks, and this doesn't happen.

Because they have been circulating their respective trajectories.

The universe is vast, the solar system is just one of countless galaxies, and the solar system is different because the earth was born as a civilized planet. Through the exploration and observation of the universe, scientists have found that there are actually many terrestrial planets in the universe, and hundreds of terrestrial planets have been discovered within the existing observation range, some of which are very similar to the earth.

Many of the new Earths that scientists have discovered in the universe are super-Earths, that is, terrestrial planets that are many times larger and more massive than Earth. Some of these new Earths are several times larger, while others are hundreds of times larger. Such a large super-earth, if humans can reach it, what a huge territory, and humans may never worry about too much population again.

The bigger the planet, the more resources, the more room for development, and of course, the more difficult it is to get to space without the gravitational pull of the planet. People envy such a super-Earth and can't help but wonder: why can't our solar system give birth to a super-Earth?

If only the earth was several times larger than it is now, the territory is bigger, and there will be no more worries about houses.

Super Earth is an upgraded version of the Earth, the volume, mass and density are far beyond the existing Earth, there are Super Earth in many galaxies in the universe, so why is there no one in the solar system, our Earth is not large in the planets of the solar system, and it is even smaller in the planet ranking in the universe. Scientists say that there is no super-Earth in the solar system, and this is mainly related to the structure of the planets in the solar system.

The boss of the solar system is the sun, and the other planets have to revolve around it, but in addition to the sun, there is also a giant in the solar system, that is, Jupiter, among the eight planets, the other seven planets are not as big as Jupiter, Jupiter's volume is 1300 times that of the earth, fortunately, it is a gas planet, if Jupiter is a rocky planet, then the solar system may not be what it is now.

Although Jupiter is a gas planet, its gravitational attraction is second only to the sun, so it is the second master of the solar system, its super strong gravitational attraction, can adsorb the surrounding matter, in the process of the formation of the solar system, Jupiter through its own power to absorb the surrounding dust Egyptian asteroids, some foreign materials become part of Jupiter, and some are crushed by gravity into cosmic particles.

It is precisely because the solar system already has Jupiter, and the distance between the earth and Jupiter is not too far, if the earth also becomes a super-earth, it will inevitably compete with Jupiter for supremacy, and the two stars will compete, and the end will not be better for anyone, and it is very difficult for the earth to become a living planet under such a competition, so the earth gave up the possibility of becoming a super-earth, and was willing to become a moderately sized planet, not competing with Jupiter, self-development with peace of mind, and finally became a civilized planet.

It's like when you're driving and saying why didn't you see yourself in a car accident! If it happens, you're gone

Why don't the 8 planets collide.

We know that the eight planets have never collided. Why don't the 8 planets collide? Some might say that this is because there are no intersections in the orbits of the 8 major planets.

At present, this statement is correct, but because the orbits of the eight planets will all be precessional, if the perihelion precession rate of the eight planets is different, the orbits of the eight planets will intersect sooner or later, and the eight planets will collide.

The perihelion precession rates of the eight planets have been observed by scientists to determine the perihelion precession rates of each planet, and these precession rates are different. Mercury precessions at a rate of 1°33 20 per 100 years, or 56 arc seconds per year. There is also a precession phenomenon at the perihelion of the Earth's orbit, with a period of about 21,000 years, about every year'。

The theory of earth expansion holds that if we look at the current perihelion precession rates of Mercury and the Earth, the perihelion precession rates of the eight planets are different, and the orbits of the eight planets will overlap. If the orbits of the eight planets had intersected, the solar system had been formed for 4.6 billion years, and the eight planets would have collided with each other a long time ago.

Why don't the 8 planets collide? The theory of earth expansion holds that if the precession rates of the perihelion of the eight planets are different, and the solar system has been formed for 4.6 billion years, it is impossible for the perihelion of the eight planets to be on the side of the sun now. Because the perihelion of the eight planets all have precession, and the perihelion of the eight planets is still on the side of the sun, the earth expansion theory believes that the perihelion precession rate of the eight planets is the same, which is the arc second per year.

Because the precession rate of the perihelion of the eight planets is the same, there is always no intersection in the orbits of the eight planets, so the eight planets will not collide.

According to the theory of earth expansion, precession is formed by the precession of the earth's perihelion, so the precession of the earth's perihelion is arc seconds. Because the precession value is more accurate, the exact perihelion precession of the Earth should be arc seconds, not approx'。Because the perihelion precession rate of the eight planets is the same, the precession rate of the perihelion of the eight planets is the arc second per year.

Thus, the observed value of Mercury's precession rate is 56 arc seconds per year and the observed value of Earth's perihelion precession rate is observed per year'is wrong.

The theory of earth expansion holds that the precession of the sun and the moon is formed by the precession of the earth's perihelion. It's like an athlete running a 200-meter circle. When an athlete returns to the finish line (starting point) after running one lap from the starting point, the referee rotates the track forward (perihelion precession) by arc seconds (i.e., precession), that is, the starting point is moved forward by arc seconds, so the athlete still has to run the corner seconds to reach the finish line (new starting point).

The original starting point is the return year, and the new starting point is the sidereal year. The athlete has already run 360 degrees by the time he returns to the finish line (the original starting point) after one lap, and 360 degrees plus arc seconds (sidereal years) when he reaches the new starting point.

The precession rate of the perihelion of the 8 planets is the same, which is the same as turning several hula circles of different sizes at a time, regardless of the size of the hula circle, the number of turns is the same, that is, the precession rate of the close point (perihelion) is the same.

Here's why:

Nine planets used to be a popular term, but since the International Astronomical Union in 2006, when it voted to downgrade Pluto as a dwarf planet, there have only been eight planets in the solar system.

In Resolution 5, adopted at the 26th session of the International Astronomical Union held in Prague on 24 August 2006, Pluto was classified as a dwarf planet and removed from the list of nine planets in the solar system. Dozens of other planets larger and heavier than Pluto did not crowd the ranks of the stars, and the solar system became eight planets, while Pluto was relegated to a dwarf planet.

Characteristics of the Eight Planets:

Jupiter-like planets, including Jupiter and Saturn, are mainly composed of liquefied gas, are much larger in volume and mass than terrestrial planets, are farther from the Sun, less dense, are located outside the asteroid belt, and have halos.

Perihelio-solar planets, including Uranus and Neptune, are between the first two in volume and mass, the furthest from the Sun, are composed mainly of solidified gases, are also densely so, have lower surface temperatures, and have halos.

Jupiter is the largest of the eight planets, enough to fit the other seven. Neptune is the farthest of the eight planets from the Sun and has a pale blue light. Venus is the second closest planet to the Sun.

Because it never rains on Venus, the entire planet is covered in dust and very arid throughout the year.

There are a total of eight planets in the solar system, in addition to the EarthMercury, Venus, Mars,Jupiter, Saturn, Uranus, and Neptune. Among them, Mercury, Venus, Earth and Mars are solid planets, or terrestrial planets, which are made of rocks, while Jupiter, Saturn, Uranus, and Neptune are gaseous planets, or Jupiter-like planets, the eight planets of the solar system.

Each has its own characteristics. <>

The composition of the solar systemThe solar system refers to the system of celestial bodies constrained by the gravitational pull of the sun, mainly by the sun, planets and their moons, and dwarf planets.

Asteroids, comets, and interstellar matter composition. The solar system is located at the center of the Milky Way.

10,000 light-years, orbiting the galactic heart at a speed of 220 kilometers per second.

Revolution, the revolution period is 100 million years. The solar system has the Sun as the main star, the mass of the Sun.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, as well as a large number of moons, dwarf planets and asteroids, occupy the total mass of the solar system.

Our solar system.

The position and distance of stars within 14 light years! Of course, for a solar system orbiting 1.5 billion light-years, this does not guarantee that there will be no stars waiting for us in the future. Since 12.6 billion years ago, the Milky Way.

Since its birth, the solar system has revolved nearly 22 times around the sun. Isn't 12.6 billion years 55 cycles? Because the solar system is only 5 billion years old, that's 22 cycles! Peace has come, and I believe the odds are low!

<> not a single star will collide with the Solar System, at least not for the foreseeable future, within light-years of the Milky Way's rotation of the Sun. The closest star to the Sun is Proxima Centauri.

But it's light-years away from us, so they're like floating on the west coast of the Pacific Ocean (the east coast of China.

and the East Coast (U.S. West Coast.

of two jars, several. There is no chance of a collision. It is common for stars to deviate from their original orbits, and Barnard's System, the second closest to Earth, is approaching the Solar System and is expected to "stop" about 6 light-years from the Solar System.

There are many three-star systems in the universe and two-star systems. Once one of them has a supernova**.

The gravitational environment around it will change dramatically, and some stars will deviate from their original ones. orbit and potentially intersect with the orbits of other stars. But because stars are so far away from us, and their orbits sweep across so much land, there's less chance of a collision than a sneeze.

Around 2020, some star collisions were visible to the naked eye from Earth.

Do a detailed interpretation of the problem, I hope it will help you, if you still have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

It should not collide with other planets, because each planet has a fixed position, so when the Duan Sun is orbiting, it is impossible to collide with other planets.

No, because the Sun has its own orbit and other stars move smoothly according to their orbits, so they will not collide.

It will not collide with other planets, because the rotation of the sun is relatively fixed, and it is also some distance from other planets.

There is no such thing as a collision, but the probability is so small that it is smaller than that of a black hole.

Have you forgotten the moon. The Moon is a satellite. Have you forgotten the sun? The Sun is a star. There are also dwarf planets and asteroids.

If we look along the Milky Way to the northeast of the sky, we see a spindle-shaped elliptical point of light. It's not a star, it's not even in the Milky Way. This is another galaxy in the Sispure universe, a galaxy that is bigger than ours, called Andromeda.

The constellation Andromeda is located 2.54 million light-years from Earth. The Andromeda Galaxy we see now is what it looked like 2.54 million years ago. When these Andromeda stars took off, our ancestors had just learned to walk upright on the African savannah.

Scientists have discovered that Andromeda is a very large spiral galaxy. It's bigger than the Milky Way. Our galaxy is about 100,000 to 180,000 light-years wide.

The constellation Andromeda is about 220,000 light-years in diameter, at least twice the diameter of the Milky Way. The constellation Andromeda contains about a trillion stars, at least twice the total number of stars in the Milky Way.

<> scientists have observed that the universe has been expanding since the big ** 100 million years ago. The distance between different galaxies is increasing. Most galaxies are moving away from us, with one exception.

This is the Andromeda Galaxy. It is hurtling towards the Milky Way at a speed of 300 kilometers per second. Scientists expect Andromeda to catch up with the Milky Way and collide in about 3.7 billion years.

The collision of two galaxies in the universe containing hundreds of billions of stars may sound quite incredible. But in recent years, observations from the Hubble Space Telescope have shown that collisions and mergers between galaxies in the Uga Space Universe are common.

The sun is the source of all things on earth. It can be said that without the sun, life on Earth would not have existed. So, how did the sun come about?

Regarding the origin of the sun, it is highly respected"Nebula hypothesis", which is believed to be the position of the Sun 4.6 billion years ago as a huge nebula, which we can call it"Solar nebula"On a certain day, the nebula collapsed, and now we see that the sun that has not been seen by Zen is condensed by the gravitational pull of the nebula material; As for the rest of the solar system, it is left over from the formation of the sun.
