Why do planets in the solar system remain in circular orbits around the sun?

Because the sun is the biggest thing in our universe, so it has the largest gravitational pull on other objects. Once that object gets into the sun's gravitational pull, the object will orbit the sun. Just like the planets. I know, IT IS A HARD CONCEPT TO GRASP!!!!!!!!!!!!!!!!!!!!

∙ 8y agoThe Sun's gravity keeps them in their orbits. Their speed takes them forward in their orbits while the Suns gravity makes them curve continuously inwards towards the Sun. The net result is that they stay in their orbits.

∙ 15y agothey stay in the same position because the suns gravity pull keeps them there

∙ 12y agoGOD makes the planets stay in place and if the planets were off too close to the sun, we would burn and if the planets were too far away from the sun, we would freeze! GOD made it just right!

∙ 11y agoi think the reson why all planets stay in orbit is because of space gravitational pull.

The shape of the path of a planet or asteroid around the sun is what?
Planets remain almost perfectly spherical as they move around the sun. The paths they follow are ellipses, with the sun at one focus of each ellipse.
Why do planets remain in orbit?
They stay in orbit because of the suns gravitational pull.
How is the speed of a planet related to its distance from the sun?
The speed of a planet varies with the distance from the Sun according to Kepler's Third Law, so that the planets closer to the Sun have higher orbital velocities. Since the gravitational effect of the Sun decreases with distance from it, the planets farther from the Sun do not have to move as rapidly to remain in orbit. (In fact, the speed is what establishes the orbit, not the other way around.) So the outer planets, in addition to having much farther to travel in their orbits, are also moving more slowly. This combination means that outer planets take very much longer to orbit the Sun than do the inner planets such as Earth. By comparison, the length of time it takes (in Earth years) for each of the outer planets to make one complete revolution around the Sun: Jupiter - 11.9 Earth years Saturn - 29.5 Earth years Uranus - 84 Earth years Neptune - 165 Earth years
Why do planets orbit the sun and not the other way around?
Actually, this is why planets orbit the sun, but not why they don't fall into it. It is the motion of the planets that keeps them from falling into the sun. Since the solar system formed from a spinning gas cloud that began to spin faster and faster as gravity squished it (gravity pulls toward the center...which is why planets and stars are round) all the planets spin around the sun (orbit) and rotate on their axis. Smaller planets close to the sun spin more slowly, because the sun's gravity has gradually slowed them down. This is also why the moon always has the same side facing the earth.Another Viewpoint:The planets have their own velocity. This combines with the Sun's gravity to produce a stable orbit around the Sun.
What two factors combine to keep the planets in their orbits?
None do. If the forces on a planet were balanced, then it would take off in a straight line at constant speed, not remain in orbit. The only force acting on a planet is the gravitational one, that attracts the planet toward the sun. Fortunately, that's the only force required to keep the planet in orbit.

A specific answer on why planets and moons of planets stay in their orbits?
Planets and moons remain in their orbits because of the gravitational pull other bigger planets or stars have on them, for example the Earth stays in its orbit because of the gravitational force it is subjects to created by the Sun, and the moon stays in its orbit because of the gravitational force it is subject to created by the Earth. It's all about gravity and force.
Why don't planets bump into each other?
because the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other.Answerbecause the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other. the planets each have defined Elliptical, not circular, orbits that remain constant because of gravitational pull of the sun and from each other. Pluto does have such an elliptical orbit that for a time it was closer than Neptune, but they will never collide with their current paths.
What are the roles of gravity in your solar system?
Gravity locks the planets into orbits, keeping them from flying off into space and permitting humans to remain on the face of the planet.
Will the planets in the milky way and Andromeda disappear forever in their collision course?
No. Most planets will remain, though a few unlucky ones may be thrown out of their orbits as stars pass relatively close to each other.
What is the importance of Newton's law of gravitation?
It explains why the planets remain in in orbit around the sun. Also, why moons orbit their planets. It also explains why humans remain on earth.
What is is the importance of newton's law of universal gravitation?
It explains why the planets remain in in orbit around the sun. Also, why moons orbit their planets. It also explains why humans remain on earth.

How can we calculate the way a planet orbits the solar system?
Planets do not orbit the solar system: they orbit the sun and remain inside the solar system.Planetary motion can be calculated from Kepler's laws.
How can you tell the Earth orbits the sun?
You can tell by the seasons, if the sun revolved around the earth the temperature would remain constant all year.
Example of gravitational force?
A. It can bring down flying objects (they fall to the Earth. The Sun attracts all the other planets so that they remain in their orbits.
How does the earth remain in its same path around the sun?
Orbits remain relatively identical for each body that orbits because neither the force of gravity between the primary and secondary have changed, nor has the momentum of the orbiting body been altered. Since both factors are the same, so is the orbit which depends on them.
