Why do the planets closer to the sun orbit the sun faster than planets farther away do?

You may recall that the force of gravity is inversely proportional to the distance between the centers of mass of the objects in question. Hence, objects closer to the sun are much more strongly attracted by the sun. They must balance that force by a stronger centrifugal force which requires a faster orbit. If they did not do so, they would just fall into the sun and be gone. Only the fast survive.

The satellite's speed is fastest when it is closest to the central body.
The satellite's speed is slowest when it is farthest from the central body.

a planet moves faster as it gets closer to the sun in orbit
a planet moves slower as it get further away from the sun in orbit

it's called general relativity

How does a planets distance from the sun affect its orbit speed?
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 outer planets take longer to orbit than inner planets?
Because gravity is stronger as it gets closer to the planet it is orbiting. and orbits are caused by the gravity of the planit they are rotating.
What does it mean to say that the planets revolve in an elliptical orbit with the sun at one focus?
that it will be faster when closer to the sun than futher away
Why does it take the outer planets so long to orbit the Sun?
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
Why do planets orbit the sun longer than other planets do?
because the farther a planet is from the sun, the longer it takes to make one orbit
Will a planet or comet be moving faster in its orbit when it is closer to or farther from the sun?
Planets and comets move faster when they are closer to the sun.
Will a planet or comet be moving faster in it orbit when it is farther from or closer to the sun?
Planets and comets move faster when they are closer to the sun.
Where in our solar system are the planets which orbit fastest?
The closer planets are to the Sun the faster their orbit speed
Planets closer to the sun orbit faster?
Yes.
What would happen if the planets farther from the sun were caused to move faster as their orbit around the sun?
The orbit would increase in size (the planet would orbit farther from the sun).
How does a planets distance from the sun affect its orbit speed?
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.

What can you draw about the properties of a planet just by knowing how far from the sun it is?
Well, the speed of it's orbit in relation to the other planets orbiting the same sun. The closer an object is to the sun the faster it's orbit. Conversely, the farther an object is from the sun the slower it's orbit.
Why do different planets have different length orbits?
Different planets have different orbit lengths because of their distance from the sun. Planets closer to the sun have shorter orbits, and planets farther away have longer orbits.
Will a planet or comet be moving faster in it's orbit when it is farther from or closer to the sun?
yes if you believe hard enough u rock my sister amal rocks alex roxs a.ka mole boy yea man rock on
Why outer planets take longer to orbit than inner planets?
Because gravity is stronger as it gets closer to the planet it is orbiting. and orbits are caused by the gravity of the planit they are rotating.
Do planets orbit fast or slow if so which ones?
The close-in ones move fast, the far-out ones move slower. It's governed by Kepler's third law.
Why does it take the pouter planets so long to orbit the sun?
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
