Orbits help a planet move because of gravitational pull which makes the planet orbit round and round. The planets orbit around the son and the moon orbits around earth.
Hope this helps!

Do the planet have orbit?
Each planet is in its own orbit and obey's Kepler's laws of planetary motion. Newton later discovered that the Sun's gravity is what makes the planets move in their orbits in the way they do.
What famous work did Kepler write explaining the way the planets move?
Kepler studied the planets' orbits and published his three laws of planetary motion, in 1609 and 1619. His most famous work was probably the 1609 book called "Astronomia Nova".
In what way is the moon like the planets?
the moon is a celestial body. that orbits the earth. though it does not have its own barycenter.
Do the outer planets circle the inner planets?
All planets circle the CEntral Star. So in a way outer planets almost circle inner planets but the Star is at one focus of the planets' orbits so it is more proper to say that planets orbit stars.
What was the the model solar system that was thought to be correct before Copernicus?
It was Ptolemy's model. Ptolemy's model came from ancient times while Copernicus's was much later (1543).Both models represented the planets' orbits by using combinations of circles and epicycles to explain the way the planets move among the stars.Copernicus found that the orbits of the inner planets could be explained more simply. That is to say that the epicycles used for all the orbits were smaller, and for the inner planets a lot smaller.Both models represented the planets' positions with reasonable accuracy given the crude observational methods used in those days.Until gravity and the laws of dynamics were discovered about 150 years after the publication of Copernicus's system, there was no way of deciding which model was the 'right' one.
What are the different way the earth move?
The earth turns on its axis; it orbits around the earth-moon barycenter; it orbits around the sun.
How planets move in orbits?
Planets move in orbits that are called ellipses, which are like slightly squashed circles. They started moving in this way even before they were planets. When the Solar System was first forming, there was just a big disk of gas and dust called the Solar Nebula. The main part in the middle became the Sun, and eventually the dust and gas collapsed under gravity to form the planets, in the same direction the disk was spinning (counterclockwise). If you want a more scientific answer, the planets are actually falling around the Sun at a rate that allows them to travel in these ellipses, which are basically just paths of curved space-time, according to Einstein.
Whast were the spheres of Eudoxus?
A mathematical representation of the orbits of the planets, configured in a way that planets would have figure eight motions that would partially explain retrograde motions.
What force works with gravity to keep the planets from being pulled into the sun?
That's "centrifugal force". It's not a "real" force like gravity, but is a convenient way of describing the effect of the inertia of the planets. (The planets would move in straight lines if they were not in a gravity field.)
What is the orbit of the sun due to gravity?
The planets' gravity on the Sun is insignificant, compared to the Sun's mass; so, within the Solar System, it is (basically) the planets that orbit around the Sun.On the other hand, the Sun - together with all the planets - orbits around the center of the Milky Way (our galaxy).The planets' gravity on the Sun is insignificant, compared to the Sun's mass; so, within the Solar System, it is (basically) the planets that orbit around the Sun.On the other hand, the Sun - together with all the planets - orbits around the center of the Milky Way (our galaxy).The planets' gravity on the Sun is insignificant, compared to the Sun's mass; so, within the Solar System, it is (basically) the planets that orbit around the Sun.On the other hand, the Sun - together with all the planets - orbits around the center of the Milky Way (our galaxy).The planets' gravity on the Sun is insignificant, compared to the Sun's mass; so, within the Solar System, it is (basically) the planets that orbit around the Sun.On the other hand, the Sun - together with all the planets - orbits around the center of the Milky Way (our galaxy).
What planet orbits the other way then earth?
All the planets in the solar system orbit in the same direction, counter-clockwise.
Which way dose Mercury orbits the sun?
Anti-clockwise when viewed from the Sun's north pole, the same way as all the other planets. Mercury's orbit is quite eccentric and elongated when compared to the other planets, however.
