How does gravity control the orbital motions of the planets in the solar system?

Each planetary body in the solar system has a gravitational effect on every other planet of the solar system as well as being affected by, and having an effect on, the Sun. Gravitational effects include tides, planet shapes, friction within a body, orbit, tilt, meteorite and asteroid impacts and avoidance of impacts, and atmospheres.

∙ 10y agoGravity is the cause of the orbits, because without gravity all the objects would travel in straight lines.
The orbit of a planet can be slightly affected by the gravity of other planets, of course. The planet Neptune was discovered by the effect of its gravity on the orbit of Uranus.

∙ 12y agoIf you are talking Orbit-Wise, gravity does not keep objects in space in Orbit, gravitational potential does! By the way, gravity in Outer Space does not exist! It is the gravitational potential that keeps the object in its place! Next & foremost, you do have gravity; however, the force of gravity is equal on Top-&-Bottom; hence, they equal out! -Dr. Miller
Technically gravity does not control anything. Gravity is a force generated by the displacement of space by mass, usually of matter. It causes all objects to attract, with more attraction to more mass. Since Sol (the sun) is the largest object in our solar system, everything in our system attracts to it, and it to everything. However, dark energy pushes everything away, causing objects to orbit around the sun, rather than just falling into it. -Dr. Moore (Ten Tibias)

What is the pull of gravity?
The pull of gravity is what pulls things down. This is on lots of planets.
How is gravity used in a sentence?
Earth has gravity rather than other planets.
What is the inward force of the sun on the planets?
gravity not to sure tho
What is an important effect of gravity?
It maintains the distances between planets.
What effect does gravity have on the outer planets?
The effect of gravity does effect the planets. Gravity keeps the planets to the sun. Gravity works between any 2 objects. It's the attraction between planets and sun that keeps planets going around the sun otherwise they would keep going in a straight line.
What is the effect on gravity on the orbital movement of planets in the solar system?
First of all, gravity causes the orbital movement in the first place - due to the attraction by the Sun, the planets go around the Sun in ellipses. Because planets also attract each other, the orbits may gradually change over time.
How did the planets get there order?
The balance between gravity (attraction to the Sun) and orbital energy (1/2 velocity2 times mass) gives the planets their order.
Why do planets have circular and elliptical motions in the solar system?
The scientific explanation lies in Kepler's laws of planetary motions, which were discovered by Newton to be linked with the law of gravity. All the planets have elliptical orbits, and many of those are close being circular.
Newton applied his laws of motion to the problem of the motions of the planets. he assumed that it was gravity that held them into their orbits. true or false?
true
What controls the motions of the planets?
Gravity is what sets the planets in motion. The force that keeps them in motion is known as inertia in the law of physics.
How do planets change orbital speed change?
Planets with elliptical orbits are affected by the difference in the strength of the Sun's gravity as they move closer to, or farther away from, the Sun. The only other major effect on planets are the gravity of other planets, notably Jupiter and Neptune. Except for Mars, Ceres, Pluto, and trans-Neptunian planets, the effect is extremely small -- it has resulted in stable orbital resonances between several small outer planets and the planet Neptune.
Why do the outer planets in the Solar System have much longer year lengths than the inner planets?
There are two reasons. First, since they are farther from the sun they have longer orbital path. Second at a greater distance from the sun the sun's gravity is weaker, giving the outer planets a slower orbital speed.
What impact does gravity have on the planets and their orbit?
Without gravity, each of the planets would continue straight ahead into space, and become dispersed. Gravity holds them in their orbital paths around the Sun. Of course, without gravity, the Sun would explode, and the planets would also disintegrate and their mass would scatter because of the centrifugal force of their spin and angular momentum.
What keeps the planets from being pulled to the sun surface by gravity?
The orbital speed of the planets prevent this. The planet's ARE all failing towards the Sun but their horizontal speed means they always miss.

How does a planets orbital radius affect its orbital period?
Yes. T = (2pi / sqroot of GM) multiplied by the radius^3/2. A planets mass DOES NOT affect its orbital period. A planets radius DOES affect its orbital period.
