First, keep in mind that all objects that weigh anything have gravity - or how much they weigh (have mass). So the earth and other planets/asteroids/comets/planetesimals 'pull' on each other, their moons, if any, and on the Sun. Of course the Sun's gravity pulls all those things toward itself, too, because it has gravity. A lot of gravity.
So actually, the Earth and all those other things are always 'falling' toward the Sun, and vice versa. The falling takes a different version in this case. We are familiar with acceleration in a straight line because we see it around us every day.
But there is another acceleration that happens to objects in orbit.
This type of acceleration is the acceleration of falling, BUT the acceleration is not the type we call 'speeding up', but the type that pushes away from the Sun (centrifugal force, or the force that makes the object (Earth) try to change to A straight line motion and fly off into space. Why doesn't the Earth just fly off into space with all that force pushing it?
Well, the other 'acceleration' is called centripital acceleration - (again, not the kind associated with speed) - which results in 'centripital force', or the pulling of the Earth and Sun's gravity towards each other. Centripital force is like the "pull" on a string tied to a ball that you are whirling around. To answer your question . . . there is a very narrow orbit in which the Earth, etc, can orbit AND keep its centripital force and the opposite centrifugal force the same (balanced). And that is exactly where Earth is.
There is nothing to change the Earth's orbit unless the Earth becomes much heavier or lighter, or the Sun becomes heavier or lighter. (That could happen in many billions of years) So as long as the Earth and Sun remain roughly at their current weights (masses), the Earth (or whatever) stays balanced in its orbit. The Sun doesn't 'do' anything about it . . . it just needs to exist and have gravity, which it does.
KEY CONCEPT: Now, if the Earth (or whatever) or the Sun did change their mass, then the Earth would simply find a little bit smaller or larger orbit size, and be in balance, again, with slightly different centripital force and centrifugal force (but still equal to each other).
What else can I help you with?
How does gravity affect the movement of the moons?
Earths gravity keeps the moon from flying off in the same way the sun keeps earth in balance.
What is the two things that keep the earth in its orbit around the sun?
The two things that keep the Earth in its orbit around the Sun are the gravitational pull of the Sun, which creates a centripetal force that keeps the Earth moving in a curved path, and the inertia of the Earth, which causes it to continue moving in a straight line unless acted upon by an external force. Together, these two forces balance each other to maintain the Earth's orbit.
Is the sun moving closer to the earth?
No, the sun is not moving closer to the Earth. The distance between the Earth and the sun remains relatively constant due to gravitational forces that keep the two bodies in their respective orbits.
How does the earth stay up in space?
The Earth stays in space due to a balance of two main forces: gravity and inertia. Gravity pulls the Earth towards the Sun, while the Earth's inertia keeps it moving forward in its orbit. This delicate balance causes the Earth to continuously move in its orbit around the Sun without falling into it.
Which force makes earth and sun stable in its orbit?
The gravitational force between the Earth and the Sun is what keeps them stable in their orbit. This force is responsible for the motion of celestial bodies in space and for maintaining the balance between their gravitational attraction and the centrifugal force of their orbit.
What to factors act together to keep earth in orbit around the sun?
The mutual gravitational attraction between the earth and the sun is the force that keeps the earth in orbit around the sun. It's the only force required, which is lucky, because it's the only force that exists.
What is the energy balance or energy budget in relation to the sun and the earth?
no
What is the energy balance and energy budget relation to the sun and earth?
no
How does gravity affect the movement of the moons?
Earths gravity keeps the moon from flying off in the same way the sun keeps earth in balance.
How does earth keep its balance in space?
The question is meaningless. "Balance" is typically what you do to avoid being upset by an external force that's trying to tip you over. There is no external force in space trying to tip the Earth over. What's more, the Earth is very close to the shape of a sphere (a ball), and balance is never an issue in the case of a sphere.
How is the energy balance or energy budget in relation to the sun and earth?
The energy balance between the sun and Earth is maintained through a process called the Earth's energy budget, where energy from the sun is absorbed by the Earth's surface and then re-radiated back into space as heat. This balance is crucial for regulating Earth's climate and temperature. Any imbalance in this energy budget can lead to climate changes and global warming.
What helped keep the earth hot?
The sun.
Why does revolve around the sun?
The sun does not revolve around the earth as was believed a long time ago. Now, with better telescopes, we know the earth, along with all the other planets in our solar system, revolve around the sun. The gravitational force of the sun pulls the planets to it and keeps them in an orbit, and the rotational force of the planets keep them from slamming into the sun. The balance from the forces of gravity from the sun and the rotational force of earth keep the earth revolving around the sun. ----------------------------------------------------------------------------------------------- As Einstein pointed out, all motion is relative, so it is perfectly true to say that the sun does revolve around the earth. However, the simplest mathematical model (in terms of the equations of motion) has the earth and the sun mutually rotating around a point that, due to the huge difference in masses of the sun and earth, is almost exactly at the centre of mass of the sun, so that it appears that the earth revolves around the sun.
Does the sun keep the earth warm?
The sun warms the earth. The heat (energy) from the earth then heats the air.
What is the two things that keep the earth in its orbit around the sun?
The two things that keep the Earth in its orbit around the Sun are the gravitational pull of the Sun, which creates a centripetal force that keeps the Earth moving in a curved path, and the inertia of the Earth, which causes it to continue moving in a straight line unless acted upon by an external force. Together, these two forces balance each other to maintain the Earth's orbit.
What do animals do to help earth?
They keep the Earth's Ecosystem in balance. and they make great companions When they are domesticated...
Does the sun's gravity keep the moon in orbit?
no the earth does
