How does planetary movement change depending on distance from the sun? - planetary
I'm just trying to help my friend with homework!
Like the motion of planets, depending on their distance from the sun? I assume that moving "slower" because there is less weight, but I know it must be even more!
Thanks in advance!

Planetary How Does Planetary Movement Change Depending On Distance From The Sun?

Motion around the sun is as easy as you said. This is the foundation of Newtonian physics. In general, the language of "water finds its own level."
In summary, a planet (the highest body mass) into an elliptical orbit of the company based on your speed and distance.
Those who do not turn into other objects as asterioids. Also been identified based on the orbits of the mass and velocity. Those not meeting the criteria that go into orbit and eventually drastically in the sun, moon or other planets may be covered, such as Mars or Jupiter.
It is highly doubtful that the moons of Mars and the asteroids come too close to Mars and the orbit of the sun instead.
The moon is moving away and one day an unknown destiny that takes the attraction of the sun, the gravity of the Earth's face.
The farther a planet is the sun, the slower the sun's path and may still be in the gravitational stability.
At each distance from the sun, there is a corresponding "escape velocity".
When a planet moves faster than the escape velocity at this distance of the planets in the solar system to leave.
But if it moves slower than the rate of release to draw the attraction of the sun on the sun.
You're right. You need to turn around the sun at a speed where the centrifugal force of the movement of the planet is balanced by the attraction between the sun and the planets. If you leave too quickly out of its orbit and eventually the solar system, and if it runs too slowly deteriorated into its orbit and eventually turns to the sun.
True - a planet, the farthest from the sun takes longer to orbit (as a "year"). At one point, the angle that each planet moves in orbit around the Sun is an industry or a segment of the path - The path segments for each planet at this moment in the region are equal. This was discovered by Kepler.
The search for Kepler's laws of planetary motion. Both Copernicus and Kepler online spent much of his working time to answer this question, and formulas are widely available and in most printed books on astronomy.
The wiki link below is a good place to start.
Two words "gravity + remote control.
