Is it possible for two planets to share the same orbit?

Why are planets round? This question is well explained, first of all, the condition is that the planet-like planet must rotate and there must be a temperature difference on the surface. The predecessor of the planet is an irregular quasar, because there is enough internal pressure to produce magma to erupt to the planet with a small radius and weak places, hundreds of millions of years later, the radius of the planet is similar or not much different, some planets have insufficient internal pressure to stop erupting, some planets have enough internal pressure to continue magma eruption, internal pressure and plate movement eventually form a planet.

The temperature difference forms the wind, which is another major force in the rounding of the planet's surface.

On August 24, 2006, the International Meteorological Symposium introduced a new definition of "planet", which consists of three main points. The first star must be a celestial body orbiting around the planet, and the vagabond who is thrown out of the system software by the gravitational slingshot effect cannot be called a planet; Secondly, its mass must be sufficiently large, so that it can get rid of the internal stress in the solid state with sufficient gravitational force and achieve the appearance of hydrostatic equilibrium (become a ball). Crooked melons and cracked dates are not qualified to be called planets.

Eventually, it must have cleared the perimeter of its orbit and had some dominion over its orbit. That is to say, there can be no higher celestial bodies within the scope of its rotational orbit, only its communication satellites. The planet begins with an accretion disk around the periphery of the initial planet, and the imbalance in the relative density of the accretion disk causes a large gravitational pull to occur in the areas where chemicals are most concentrated.

As a result, vapor and floating dust gradually accumulate in these high-density areas, and the newly formed clumps are collided with other clumps, or are destroyed, or combined. Until a mass is too large to be destroyed by a small-scale taxpayer collision, the core of the planet is created.

Thinking about the evolution of the universe, we need to first throw away our habitual time and frequency domains, because our lives are too short. It is unlikely that the two protoplanets will operate at exactly the same rate, and even the slightest difference will be more and more impressive if the difference is multiplied by billions of years, even if the orbits of the two celestial bodies only have two junctions. After a long time, they will not bump into each other, just like the earth and "Theia" when they were young; Either they will be "ejected" into other orbits by the gravitational attraction of each other, or even thrown to the edge of the planets of the solar system, and become the "dwarf planets" in the Kuiper Belt today.

In short, it is unlikely that they will be okay in the long term.

For example, the calculation of the orbit between the earth and the sun, and the calculation of the orbit between the earth and the moon, are all estimated based on the gravitational effect between the two celestial bodies, and the harm of sunlight to the orbit of the earth and the moon can generally be ignored, or brought in as a whole, and it is impossible to estimate it as three separate celestial bodies. The operation of two or more celestial bodies in the same orbit is called orbital high-pressure common orbit, which is an unstable situation in astrostructural mechanics, which belongs to the three-body problem in celestial structural mechanics. We usually study the fitness exercise of celestial bodiesGenerally, it is optimized into a two-body problem, that is, the structural mechanics calculation and orbital fitness exercise between the two celestial bodies.

It is impossible for two planets to share the same orbit. Because they share the same orbit, it is easy for planets to collide.

Two planets sharing the same orbit will not be truly stable, at best it will be quasi-stable, which means that after a certain amount of time, the equilibrium will be broken. But before this hand-to-hand fight, two planets could theoretically share the same orbit for billions of years.

It is impossible for two planets to share a common orbit. As long as the sun is still in the eight slags, it can run stably in its respective orbits, and two planets sharing the same orbit will not be truly stable.

Summary. Hello, dear <>

According to the question you provided, does it contradict the ratio of two planets in the same orbit to their orbit for you to find out the following: It is impossible for two planets to be in the same orbit, because the orbit of a planet is determined by its mass and the interaction of other objects in space. If two planets have the same orbit, they will collide in that orbit, and due to the enormous energy of the impact, this will have devastating consequences.

Therefore, there is no such thing as two planets in the universe where their positions exactly coincide. If two planets have close orbits, they may stagger, but they will not be in exactly the same orbit. <>

Does the two planets in the same orbit contradict their orbits?

Exercise question on gravitational force, what is the ideal pattern of two planets in the same orbit but at different distances from the orbit of the central celestial body.

If two planets are in the same orbit but at different distances from the central body, their orbital radii are different, and their orbital periods will be different. According to the law of gravitation, the magnitude of gravitational force between two objects with masses of $m 1$ and $m 2$ and a distance of $r$ is $f=g frac$, where $g$ is the gravitational constant. Thus, the orbital period of the two planets can be calculated by the following formula:

t=2 pi sqrt}$, where $a$ is the orbital radius, and $m 1$ and $m 2$ are the masses of the two planets, respectively. Because the two planets are in the same orbit, the period of their revolution around the central celestial body should be equal, so we can find the relationship between the orbital radius of the two planets $a 1$ and $a 2$ by this formula: $ frac= frac$ Therefore, we can draw a graph of the relationship between $a$ and $t$, and when $m 1$ and $m 2$ are known, we can use this graph to estimate the relationship between the orbital radius and the orbital period of the two planets.

Since the two planets are in the same orbit and their orbits are similar, this diagram should be a straight line with a constant slope.

Suppose in the universe.

At the initial stage, the planets are chaotic and disorderly, at this time the planets feel the gravitational pull of other planets and the sun, of which the gravitational pull of the sun is the strongest, so the planets are restrained by the sun, and at the same time feel the weak gravitational pull of the smaller planets, which keeps the three on the same plane, but strictly speaking, the eight planets are not on the same level, and there are very small differences between them, but they can be ignored, and this site to learn about it.

Speaking of this question, it seems very complicated, and it sounds a little more difficult to understand than the previous talk about why the orbit of the planet is elliptical. If we consider that when the solar system was first born, all the planets were in a state of chaos, with their own paths, and there was no fixed orbit for everyone.

At this time, the planets will feel the gravitational pull of the sun at the same time, and at the same time the gravitational pull of other planets. Of course, the gravitational pull of the sun is the greatest, and the gravitational pull of each other is nothing.

Planets and other planets interact with each other to form a mutually restraining force. Smaller planets feel the gravitational pull of the Sun, while other planets have weaker gravitational pulls. Over time, the three celestial bodies are basically on the same plane.

The same is true of the other planets in the solar system, where under the influence of each other, they can finally succeed in preserving a plane, and everyone is roughly the same.

Are there any other different situations?

Strictly speaking, however, the eight planets are not completely preserved in one plane. For example, the orbits of Mercury and Uranus will also have a certain difference from the Sun, but the angle is not too large, and it is basically negligible, so it is okay to say that they are all in the same horizontal plane.

The entire solar system revolves around the sun, and the planets interact with each other, and in the end, the combined forces of everyone will remain roughly on the same plane.

Therefore, strictly speaking, the eight planets all orbit in one plane, of course, it is not a complete plane, and the general direction is relatively consistent.

1. The asteroid belt is a dense area of asteroids in the solar system between the orbits of Mars and Jupiter. Counting the 120,437 asteroids that have been numbered, all of which have been discovered here.

2. In the early stage of the formation of the solar system, due to the common collision of the accretion process, the small particles gradually gather to form a larger cluster, and once they gather enough mass (that is, the so-called microstar is lacking in the stool posture), they can use gravity to attract the surrounding matter. These stars can steadily accumulate mass and become rocky planets or giant gas planets. The mystery of the asteroid belt is unsure when it will be solved.

However, a growing number of astronomers believe that asteroids record information about the early days of the formation of planets in the solar system. Therefore, the origin of asteroids is an important and inseparable link in the study of the origin of the solar system.

All the stars in the solar system, when born due to gravity, reach equilibrium by rotating around the center of mass, and the angular momentum of this rotation is conserved. The result is a two-dimensional plane in which the upward and downward momentum cancel each other out and all the axes of rotation converge. The reduction of rotation from four to three dimensions is not only the solar system, but also the Milky Way, although the accretion disk of the black hole will appear to be roughly in the same plane as the Burning Wheel.

<> fact, it is not a special case of the solar system that the planets are basically kept in a plane around the stars, but a relatively common phenomenon, and the orbits of the planets around other stars are basically kept in a plane, and the reason is related to the formation of stars and planets. The current mainstream theory about the formation of celestial bodies is that celestial bodies are formed by the condensation of nebulae. Of course, there are some more detailed differences under this theory, but the main idea is that the earliest form of celestial bodies was nebulae, which were formed by the condensation of nebulae to form stars and planets.

In this process, the nebula rotates under gravity, forming the spin axis and the equatorial plane, so that more material is gradually concentrated in the equatorial plane, while less material is at the poles of the spin axis. When stars are formed, the rest of the material is mostly at the equator, and as the temperature decreases, planets form.

As a result, the orbits of these planets are also close to the equatorial plane, and over time, the planets gradually empty the material from their orbits, eventually forming systems like our solar system, where the orbits of the major planets do not deviate too far from the equatorial plane. Only those more distant fragments, weaker by gravity, are not concentrated near the equatorial plane, but are scattered throughout space. Or something special happened, such as a collision that pushed the planet away from the equator, or an alien planet may have moved away from the equator.

Do a detailed interpretation of the problem, I hope it will help you, if you 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 also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Because each planet has its own orbit, there will be a gravitational force between the planets, and then the angle of the sun when it revolves is limited, otherwise it will deviate from the orbit, and then it will be affected by the angular momentum, so that the sun will not condense under the action of gravity.

This is due to the magnetic field in the universe, and the nine planets have a certain gravitational pull on each other, so they are almost on the same plane.

This is due to gravity, which is why most of the planets orbit stars.

If the two planets interact dynamically, then in very special cases it is possible; If the two planets have no influence on their dynamics, then they cannot be in the same orbit, because the slightest external influence can cause the subsequent orbits to change dramatically.

In the eight planets of the solar system, each planet has its own orbit, and there are no other planets in the same orbit (except for asteroids), so would there theoretically exist two planets in the same orbit?

If the two planets do not dynamically affect each other, but are independently located in different positions in the same orbit, then the orbit of the two planets is unstable, because if any planet is slightly affected by the outside world, its subsequent orbits will deviate greatly, and eventually the orbits of the two planets will differ more and more, or even collide.

In the past, it was rumored that the earth is on the other side of the sun, there is a sister star of the earth, due to the obscuration of the sun we can't see each other, but a little bit of astronomical knowledge, know that this statement is not reliable.

It is possible for two planets to be in the same orbit if they are dynamically influencing each other and form a special orbit, such as in the following two cases:

1. Biplanetary system.

That is, two planets orbit each other, and then they orbit farther away from the star, there is no such planetary system in the solar system, but Pluto and its moon Charon, a bit like this, a double planetary system.

Pluto is a dwarf planet, he has five confirmed moons, of which Charon is also called Charon, Charon's mass is one-eighth of Pluto's, and its diameter is half that of Pluto.

Then there is a situation where two planets of comparable mass form a double planetary system and then orbit the star in the same orbit, and we can say that the two planets share a common orbit.

2. Celestial bodies at the Lagrange point.

In Jupiter's orbit, there are two regions of asteroid groups, called the Trojan Group and the Greek Group, which form equilateral triangles with Jupiter-Sun, respectively, the fourth Lagrange point (L4) and the fifth Lagrange point (L5) of Jupiter and the Sun.

The objects at these two points are dragged by the gravitational pull of Jupiter and the Sun, and are dynamic equilibriums, and if there are exactly two planets of comparable mass in a star system, each at each other's Lagrangian point, then it is possible for them to orbit in the same orbit.

In practice, it is difficult for planets with comparable mass to meet this condition, but for some massive planets, it is easy to attract some asteroids to these two dynamic equilibrium points.
