Gravity attracts masses together, especially large masses. So all planets are attracted towards the Sun. The Sun is attracted likewise towards the planets, but as the Sun has a much larger mass than any of the planets, the Sun is moved extremely little by the gravity of the planets.
The planets also have a large speed perpendicular to the direction to the Sun. This is their orbit speed. If they did not have that perpendicular speed, they would quickly be drawn directly towards the Sun and be absorbed completely by the Sun. But because of the combination of the perpendicular speed and the gravitational pull from the Sun, the planets are kept in their orbits.
And because the planets move in almost a perfect vacuum, there is nothing to slow down that speed. So the orbits are as good as permanent.
It is, by the way, exactly the same situation that keeps the Moon rotating around the Earth, or any other moon rotating around its planet.
The orbital speed of the Earth around the Sun is about 29.8 km/s in average. So, we all move at the amazing speed of 30 kilometers per second around the Sun! That is around 107,000 km/h or 66,700 mph. We completely owe our life to that speed. If Earth stopped, the Sun would quickly absorb us. :o)
What else can I help you with?
Does gravity keep the planets orbiting the sun?
Yes.
What helps keep the planets orbiting the sun?
The planets orbit the sun due to gravitational attraction. The sun's massive gravity pulls the planets towards it, while the planets' tangential velocity allows them to move in a circular or elliptical orbit around the sun. It's essentially a balance between the inward force of gravity and the outward force of the planets' momentum.
The earths gravity keeps the planets circling the sun?
Actually, it's the gravity of the sun that keeps the planets in orbit around it. The force of gravity between the sun and the planets causes them to be pulled towards the sun, while their momentum keeps them moving in a circular or elliptical path.
How does the sun have gravity?
The sun has all the gravity to keep the planets a certain distance from the sun.
What makes the planets orbit around the sun?
The gravitational pull between the planets and the sun keep the planets orbiting the sun all day everyday.
Is there gravity in a vaccum?
yes, since the sun has the planets orbiting around it, and there is a vacuum in between, that proves it.
Does gravity keep earth in its orbit?
Yes; the sun's gravity keeps the Earth orbiting around it.
Who believed that forces keep moons orbiting planets and planets orbiting the sun?
Isaac Newton stated that the universal law of gravitation keeps moons orbiting planets and planets orbiting the sun. This law describes how every mass attracts every other mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
What two forces work together to keep the planets in orbit around the sun?
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
Could you name the forces the earth to orbit the sun?
The force of gravity keeps the Earth (and all the other planets) orbiting the Sun.
Where does force needed to keep planets orbiting the sun come from?
The force is provided by the Sun's gravitational attraction.
Why do the 8 planets keep orbiting the sun?
The 8 planets continue to orbit the sun due to a balance between the sun's gravitational pull and the planets' forward motion, which creates an elliptical orbit. This balance allows the planets to constantly move around the sun in a stable manner.
