What forces drive the nine planets around the sun

To put it simply, it is gravity.

But gravitation only explains the phenomenon, not the essence: what causes gravity?

It seems to be macroscopic, but in fact, due to the binding effect of various forces on the spotter, you can learn more about quantum mechanics.

In addition, general relativity believes that the essence of gravity is the curvature of space-time, and these planets move in a straight line, and they are not elliptical, because all the planets are slowly approaching the sun, provided that there is no greater external force, and the sun is the same, it is revolving around the Milky Way.

Universal gravitation. The macroscopic structure of the entire universe is sustained by gravity.

There are four forces in the universe, gravitational force, electromagnetic force, strong interaction force, and weak interaction force.

The latter two forces are present in the nucleus of an atom. The macroscopic forces are only gravitational and electromagnetic.

Summary. There are eight planets in the solar system, which are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The first four belong to terrestrial planets, which are small, dense, and solid, while the last four belong to Jupiteroids, which are large, dense, and gaseous. In terms of the orbital radius of Neptune, the farthest planet, the eight planets, as well as the Sun, are distributed within a near-circle with a radius of about 30 astronomical units.

The Sun is a star, so what are the eight planets orbiting it?

Hello. The eight planets orbiting the Sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Oh yes! There are eight planets in the solar system, which are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The first four belong to terrestrial planets, which are small, dense, and solid, while the last four belong to Jupiteroids, which are large, dense, and gaseous. In terms of the orbital radius of Neptune, the farthest planet, the eight planets, as well as the Sun, are distributed within a near-circle with a radius of about 30 astronomical units.

The eight planets refer to the eight planets of the solar system, which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in descending order from near to far. Most of the eight planets also rotate in the same direction as their orbit. There are only two exceptions: Venus and Uranus.

Venus rotates in the opposite direction to its revolution. Whereas Uranus rolls in orbit. Pluto, once considered one of the "Nine Planets", was defined as a "dwarf planet" on August 24, 2006.

Definition of planets: first, celestial bodies that must orbit stars; Second, the mass is large enough to rely on its own gravity to make the celestial body spherical; The third is that there should be no other objects near its orbit. According to this division, there are only eight planets in the solar system: water, metal, earth, fire, wood, and earth, plus Uranus and Neptune.

In contrast to the concept of nine planets mentioned before 2006, Pluto was classified as a dwarf planet and removed from the list of nine planets in the solar system in Resolution 5 adopted at the 26th International Astronomical Union in Prague on 24 August 2006. It must be a celestial body orbiting the star - Pluto coincides. The mass is large enough to rely on its gravitational pull to make the celestial body appear spherical, but Pluto has not been able to clear other objects in its orbit and is therefore downgraded to a dwarf planet.

Celestial bodies that also have sufficient mass and are spherical in shape, but cannot clear other objects in the vicinity of their orbits are called "dwarf planets", and Pluto fits this definition and has been recognized as a "dwarf planet" by the International Astronomical Union. So Pluto is classified as a dwarf planet. Since then, there have been only eight planets in the solar system.

For the same object, assuming that the gravitational force of the Earth on it is 1, then the gravitational force of the Asteroid in the Eight Sources Chain Hall can be expressed as follows.

Earth 1 Mercury.

Venus Mars. Jupiter Saturn.

Uranus Neptune.

That is, if an object weighs 100 N on Earth, it is 37 N on Mercury, 88 N on Venus, and so on.
