How strong is the gravitational pull of the Sun and how many stars revolve around the Sun?

There is no way to estimate the gravitational pull of the Sun in an exact number, but what we do know is that the Sun is the core of the entire solar systemAll the planets in the solar system revolve around the sun or are affected by the sun's gravity, and at least eight planets are strictly bound by the sun's gravity. <>

The one revolving around the sun is a punishment, not a star, because there is only one star in the entire solar system, the sun is the meaning of the star, which is almost fixed in space, and the position of the small instrument where he is located is relatively stationary, and then it can emit light and heat the central celestial body, but there is only one star in the entire solar system, so there is no star rotating around the sunAll planets or moons revolve around the sun. Because different celestial systems have different definitions of planets and moons. <>

The sun can become the core of the entire solar system, and become the only star in the solar flag, because the sun itself has a large mass, the sun occupies 90% of the mass of the entire solar system at the beginning of its formation, and its volume itself is not so large, at least relative to the earth, its density is much greater than the earth, so it leads to his high pressure on space, forming a very large gravitational force, and all the premises in the entire solar system must be bound by the sun's gravityIt's just that the planets of the Sun are less affected by the planets of the Earth, such as the Earth's Moon. <>

The sun's gravity is the most critical force to maintain the stable balance of the entire solar system, and the reason why so many celestial bodies can operate in a safe and orderly manner without colliding is because the various celestial bodies have been bound when the sun was formed many, many years ago, and can only run in a fixed orbitHe can't go wherever he wants, of course, he is not simply good, the disadvantage is that if human beings want to fly out of the solar system, the first thing to do is to overcome the influence of the sun's gravity on objects.

The gravitational pull of the sun is huge, and there are many planets around it. No star revolves around the Sun because the Sun is the only star in the solar system.

The gravitational pull of the sun is so great that the eight planets, including the earth, revolve around it, the sun is a star, there should be no stars revolving around the sun, most of them are planets.

Because the gravitational pull of the sun is so strong, it can make many planets revolve around it. But there are no stars in these planets, only planets.

f=g·m1·m2/r^2=。

The gravitational force between the sun and the earth is the contribution of the product of the masses and the square of the distance, and the attraction between the two satisfies the formula, which Newtonian mechanics interprets as the interaction and reaction force of these two forces, which naturally satisfies the three laws of the ox.

The gravitational effect is inversely proportional to the square of the distance. Its essence is that the gravitational effect is radially isotropic and the spherical surface is equivalent to divergence. The gravitational effect emitted by the mass substance, the sum of the sum (integral) at each point on the surface of each of the closed bodies that surround it, is the same independent of distance, that is, the sum of the surfaces of the closed body, that is, the total amount, is equal and unchanged, independent of the shape of the closed body.

Let the closed body be a sphere, then the total amount is the surface area x the components of each point, and the components of each point are the total surface area, and the surface area is proportional to the square of the distance (half longitude). The component of each point on the surface is equal to the square of the total distance.

So at each point, the gravitational effect is inversely proportional to the square of the distance.

Therefore, the gravitational effect is proportional to the mass product of both sides and inversely proportional to the square of the distance, and together with the gravitation constant, Newton's second law is obtained, the formula for the vertical gravitational force of universal land:

f1=f2=g mi mj r=gm1m2 r, equal.

Question 1: How strong is the gravitational pull of the sun? The magnitude of the force is related to the mass and distance of the two objects that are attracted to each other.

The greater the mass, the greater the gravitational pull. The smaller the distance, the greater the gravitational pull. The space station can float in the air because the space station rotates at a certain speed, and the astronauts are not sucked back to the ground, because the mass of the astronauts is too small, and after reaching a certain altitude, the gravitational force between the space station and the earth is too small to be basically negligible, so it is not sucked back.

Weightlessness is also due to the large distance, and the gravitational force is negligible, but it is not without gravity.

Question 2: How big is the gravitational force between the Sun and the Earth The average gravitational force between the Sun and the Earth: f=gmm r 2= ( n=

Question 3: What is the gravitational pull of the Sun on the Earth The average value of the gravitational force of the Sun and the Earth: f=gmm r 2= ( n=

Question 4: How much does the sun's gravitational pull control There are no obvious boundaries, and all objects in the solar system are subject to the sun's gravitational pull. Moreover, gravity is a long-range force, and theoretically, only if it is not infinitely far from the sun, it will be subject to the sun's gravitational force.

Question 5: What is the gravitational range of the solar system The boundary radius of the solar system is determined

1.With Pluto's orbit as the boundary, it is about 40 astronomical units.

2.According to the comet's origin hypothesis, the Kuiper Comet Belt is 50 1000 AU; The Oort cloud, which is 100,000 astronomical units light-years.

3.According to the heliopause, it is 100 160 AU.

4.The theoretically calculated gravitational range of the solar system is 15,230,000 astronomical units.

Note: 1 astronomical unit is about 100 million kilometers.

1 light year is about a kilometer.

When it comes to the system hierarchy of celestial bodies, there are three types, stars, planetary satellites, but satellites, I think it is a relative thing, not an absolute thing, but stars and planets are the most obvious classification, the sun is a star, that is, it will not go, at least in our opinion, it will not go, and then the planets will move.

Not all planets revolve around the sun, only the solar system.

The planet is the solar system that revolves around the sun, originally there were nine planets, which later became eight planets.

Water, gold, earth, fire, earth, Uranus, Neptune.

Pluto, who later kicked Pluto out, became the eight planets, and these 8 planets really orbit around Wu Weifeng's sun. And then the other 8 planetary moons orbit around their respective planets, for example, the Earth, the Earth orbits the Sun, but the Earth also has its own moon, the Moon.

The Moon orbits the Earth.

The position of the sun in the universe is not the same nor the sun, although it is called a star, it is not that it is absolutely immovable, but from the perspective of the solar system, we all revolve around the sun, and the sun is immobile. But from the whole galaxy.

From the point of view, the sun will move, it should be said that it is the entire solar system that will move, and the entire galaxy is similar to a small galaxy like the solar system, there are at least 2000 ones, this is only the Milky Way, and there are other large galaxies of the same level outside the major galaxies? For example, the Milky Way's neighbor, the Andromeda Galaxy, contains two or more small galaxies that are more than twice the size of the Milky Way.

The universe is very big, so big that we can't imagine it, because we live on the earth, look at the mountains and the endless seaside, look at the vast sky, and feel that the world is already very big, but putting human beings in the universe is really a very inconspicuous, a dispensable existence. Human beings are attached to the earth, and without the earth, human beings cannot live, but the earth is the same as the earth without human beings, and the solar system has no human beings, the same solar system, human beings themselves have their own consciousness and their own civilization, and we will also think about the relationship between man and nature, the relationship between man and the universe, but in essence, we are the one who adapts to the environment, not the one who changes the environment.

The Sun is the center of the solar system, and basically all the high-altitude planets, comets, dwarf planets, asteroids, Mite, and other celestial bodies in the solar system revolve directly or indirectly around the sun. For example, the eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, all revolve around the Sun.

There are 8 in total, including Earth. The eight planets were formed from material that revolved around the Sun about 4.6 billion years ago. Mercury, Venus, Mars, Jupiter, and Saturn can all reflect the sun's rays and glow, so they can all be seen with the naked eye.

To observe Uranus and Neptune, you need to use a telescope.

The gravitational pull of the Sun on the Earth is directly proportional to the product of the masses of the two and inversely proportional to the distance between the two.

The law of universal gravitational force is the law of gravity that explains the interaction between objects.

The law states that any two particles are attracted to each other by a force in the direction of the concentric line, and that the magnitude of the gravitational force is proportional to the product of their masses and inversely proportional to the square of their distances, and has nothing to do with the chemical or physical state of the two objects and the intermediary matter.

Galileo had actually put forward the initial idea of centrifugal force and centripetal force in 1632, Briard proposed the idea of the square ratio of gravitational force in 1645, and Newton proved the law of centrifugal force in his own way in his manuscript, but the word centripetal force probably first appeared in the first manuscript of On Motion.

If it is considered that the planets move in a uniform circle around the Sun, then the gravitational pull f of the Sun on the planets should be the centripetal force experienced by the planets, i.e.

f=mv^2/r

where r is the distance between the sun and the planet, v is the linear velocity of the planet's motion, and m is the mass of the planet.

The relation v=2 r t of the period t and velocity v in circular motion

Substituting the above equation is f=4 2(r 3 t 2)m r 2

According to Kepler's description of the laws of planetary motion, r 3 t 2 is a constant, so it can be concluded that the gravitational force between the planet and the sun is directly proportional to the mass of the planet and inversely proportional to the quadratic of the distance from the planet to the sun.

According to Newton's third law, the force of a planet to attract the Sun is equal in magnitude and has the same properties as the force of the Sun to attract a planet. Newton believed that since this gravitational force is proportional to the mass of the planet, it should of course also be proportional to the mass of the sun. Therefore, if you use m'Indicates the mass of the sun, then there is.

f∞m'm/r^2

Written as an equation, it is f=gm'm/r^2

g is a constant, which is the same for any planet.

Newton also studied the motion of the moon around the earth and found that the gravitational pull between them followed the same law as the gravitational pull between the sun and the planets.

Newton studied the gravitational attraction of many different objects that follow the same law, and further extended this law to any two objects in nature, officially publishing the law of universal gravitation in 1687

Any two objects in nature are attracted to each other, and the magnitude of the gravitational force is directly proportional to the product of the masses of the two objects and inversely proportional to the quadratic of their distance.

If m1 and m2 are used to denote the masses of two objects, and r is used to denote their distance, then, the law of universal gravitation can be expressed by the following formula:

f=gm1m2/r^2

The unit of mass is kg, the unit of distance is m, and the unit of force is used as a constant, which is called the gravitational constant, which applies to any two objects, and it is numerically equal to the interaction force when two objects with a mass of 1kg are 1m apart, and the standard slow value of the gravitational constant is g=

Usually taken. g=6367*10^-11nm^2/kg^2

The gravitational pull of the Sun on the Earth is about x 10 22 Newtons (about x 10 21 kgf).

This gravitational value is very huge and it is created due to the mass attraction between the Sun and the Earth. The quality of the Sun is relatively large, and it is very close to the Earth, so its gravitational pull on the Earth is very strong. This gravitational pull allows the Earth to maintain a stable orbit in the solar system.

The Sun is a yellow dwarf star, also known as a g-type main-sequence star. It has a diameter of about 1,390,000 km and a mass of about 2x10 30 kg. The Sun is one of the most important objects in our solar system, and its gravitational and radiant energy provides planets like Earth with the energy and environment they need to survive.
