What keeps the planets in orbit around the sun?
Gravity, combined with the velocities of the planets, keeps the planets in orbit around the Sun.Gravity between any body, such as a planet, and the Sun is one factor. Also the planet has a velocity. These two things combine to keep the planet in orbit around the Sun.Gravitation. The suns gravitational pull. The huge mass of the sun means it has a huge gravitational pull, keeping all of the planets in place. There is also the planets velocity that would take the planet away from the sun if there was no gravity, so these two forces act against each other.
Do all the planets have smaller planets orbiting them?
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
How are the planets held in their orbit?
Planets are held in their orbits around the Sun by gravity. The gravitational pull from the Sun keeps the planets moving in their elliptical paths. This balance between the planet's velocity and the gravitational force from the Sun keeps them in a stable orbit.
Do the stars orbit the planets or do planets orbit stars?
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
Do all planets orbit the moon?
No. The planets orbit the sun.

How is a planets distance from the sun affects its velocity?
The farther a planet is from the sun the slower its orbit speed.
Are satellites an example of acceleration as it orbits around the earth?
Yes. Since the velocity changes all the time, there is an acceleration. The acceleration is towards the center of the Earth. Note that the speed need not change; velocity consists of a speed (magnitude) and a direction, and in a circular orbit, it is the direction that changes.Yes.

If the gravitational pull of the sun is the most then why doesn't it pull the planets towards it?
It does. The planets have velocity and inertia that keep them in orbit; but they really ARE continuously falling towards the Sun, their velocity makes them miss it constantly though!
What keeps the planets in the Sun's orbit?
Gravitational force, combined with the velocities of the planets. The force from the Sun is pulling the planets toward it, but the velocity of each planet is acting against this. The result is that the planets orbit the Sun. (The question is a bit mixed up, but it seems obvious what it's about.)
How does gravity affect the motion of objects on planets orbiting the earth?
You know that no planets actually orbit the earth right? ...?
Do stars orbit planets or planets orbit stars?
Planets orbit stars.
Do all the planets have smaller planets orbiting them?
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
Gravity is the reason that the planets stay in orbit around the sun?
It is half the reason, at least. Gravity is the force pulling the planets towards the sun, but they also have a velocity working perpendicular to it. With the velocity alone, the planets would fly off into space. With gravity alone, the planets would be pulled into the sun.
How are the planets held in their orbit?
Planets are held in their orbits around the Sun by gravity. The gravitational pull from the Sun keeps the planets moving in their elliptical paths. This balance between the planet's velocity and the gravitational force from the Sun keeps them in a stable orbit.
What path do planets orbit the sun?
Planets orbit the Sun in elliptical paths, as described by Kepler's First Law of Planetary Motion. While these orbits are not perfect circles, they are generally close to circular for the major planets. The gravitational pull of the Sun keeps the planets in their orbits, and the specific shape and orientation of each orbit are determined by the planet's velocity and distance from the Sun.
What keeps a planet in its constant orbit?
There are two factors that are balanced just right to keep the planets in their orbits; the tangential velocity, and the gravity. The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force is constantly attracting the planets in, against this tangential velocity. If the planets were to slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.
