How do the orbits of the outer planets compare to the inner ones?
The outer planets take much more time and also travel longer to complete a whole orbit around the Sun, than the inner ones.
When planets orbit a star?
When don't they? If a planet is in orbit around a star, it is in continual orbit. Orbital periods (the lengths of time it takes different planets to complete one orbit) are different from planet to planet, and are related to the distances between the planets and their stars.
Why do the planets orbit in many different planes?
The planets in our solar system orbit in different planes because they formed from a rotating disk of gas and dust around the young Sun. The angular momentum of this rotating disk caused the planets to form in different planes. Over time, gravitational interactions between the planets and other celestial bodies can further perturb their orbits, leading to even greater differences in orbital inclinations.
Why did terrestrial planet move rapidly in there orbits?
Terrestrial planets move faster in their orbits because they are closer to the Sun. Isaac Newton, who discovered the effects of gravity, stated that gravity gets stronger the closer you get to a large, massive body (like the Sun) - and this makes the planets orbit faster than the outer planets, where the force of the Sun's gravity is less. Their orbits are also smaller, so it takes less time for them to go around the Sun.
Why does it take Pluto the longest time to make a complete revolution around the sun?
Pluto has the longest orbit in length as it is further away from the sun than the other planets. If we model the orbit of all the planets as perfect circles, we can see that planets further from the sun give orbits which are larger circles, and larger circle have larger circumferences, which are the longer orbits. Even if the planets orbited at the same speed, Pluto would take longer to orbit as it has further to travel. Pluto doesn't orbit at the same speed as other planets - it orbits more slowly. This means it takes even longer to orbit the sun. It orbits more slowly as it is further out and the sun exerts less of a gravitational force on Pluto than on the other planets, and it is this gravitational force which causes objects to orbit around the sun. In fact, the sun exerts 1600 times as much force on Earth than on Pluto.
Why do planets move in different direction?
Planets have to go in different directions all the time because they all follow orbits that are more or less circular.
Why planets do not all orbit the sun at the time?
They are all orbiting the Sun, "at" the same time.But they don't complete their individual orbits "in" the same time.This is because they are ...* different sizes; * different distances from the Sun; * travelling at different speeds.
Do planets take turns orbiting?
No. The planets all orbit the sun at the same time. The planets occupy different orbits at different distances from the sun so they do not affect one another significantly.
What planet is known as the fastest?
It depends what you are referring to. No planet is known as the fastest. Planets rotate at different speeds, their orbits take different amounts of time.
How do the orbits of the outer planets compare to the inner ones?
The outer planets take much more time and also travel longer to complete a whole orbit around the Sun, than the inner ones.
How does Charon's orbit around Pluto different from the orbits of most moons around their planets?
Charon orbits once every time Pluto rotates once. Other moons(including ours)don't do that.
Which is determined by the force of gravity?
-- Your weight is, as long as you're standing on the Earth or some other planet, but it's different in different places. -- Also, the speed of the moons, comets, asteroids and planets in their orbits, and also the length of time it takes them to revolve in their orbits.
How much time does it take for the planets to complete one revlution around the sun?
Each planet has a different time phase.
When do planets orbit a star?
When don't they? If a planet is in orbit around a star, it is in continual orbit. Orbital periods (the lengths of time it takes different planets to complete one orbit) are different from planet to planet, and are related to the distances between the planets and their stars.

What two planets are next to the astroidbelt?
Most of the asteroids spend most of their time between the orbits of Mars and Jupiter.
Do all planets stay in one place or do they revolve in orbit?
The planets turn about their axes (rotate), and move in orbits about the sun (revolve). They are all in dynamic motion all the time. Welcome to the music of the spheres. Planets (all of them) are continually in motion. They all revolve on their axes and move about the sun in their orbits. This is the music of the spheres.
