What causes the planets that are closer to the sun to move faster?

Basically it is because the force of gravity is greater nearer the star so it acclerates the star even more. A more mathematical answer: The force of gravity is given by the formula F = GMm / r^2 Where G is a really small number used as a constant of proportionality, M is the mass of the star, m is the mass of the planet and r is the distance between them. The force of gravity is acting as a centripetal force on the planet and we know that for a centripetal force is F = mv^2 / r Where v is the velocity (speed) of the planet. We can combine the two formulas to give v = sqrt(GM / r) So a planet will move faster if the star is more massive or it distance from the star is smaller.

∙ 12y agoThat's one of Kepler's three laws of planetary motion, which he figured out from
studying Tycho's lifetime of watching the planets and keeping notes.
About 100 years after Kepler, Newton wrote his theory of universal gravitation,
and showed that if gravity is true, then the planets mustbehave that way.
The best direct answer to your question is: Because that's how gravity works.

∙ 13y agoThe pull of the Sun's gravity is stronger the closer you get to it, so the planets need to orbit faster to resist the pull. If they didn't go as fast, they would be pulled into the Sun and be incinerated. The Sun also keeps them in the same orbit. If they were faster or were farther away, they would resist the pull of gravity and fly into space.

∙ 12y agoplanets closest to the sun move faster because the suns gravitational pull is stronger then the outer planets that is also why the outer planets are more cold because the suns heat is lost more.

So, the planets have to move faster to keep in stable orbits and not fall into the Sun.

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 do some planets travel faster than others?
The speed at which planets travel in their orbits depends on their distance from the sun and their mass. According to Kepler's laws of planetary motion, planets closer to the sun orbit at higher speeds because they experience a stronger gravitational pull. Additionally, planets with less mass also tend to move faster as they are less influenced by the gravitational pull of the sun.
Do planets revolve faster or slower when they are close to the sun?
They move faster.
Why do planets move across the night sky but stars don't?
The planets are closer. (They all move - and differently.)
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
How do planets move if they are closer to the sun?
faster.
Kepler discovered that planets move faster when they?
Closer to the sun.
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.
What causes the planets that are closer to the sun move faster?
since it is closer to the sun it gets around the sun faster cause it has less of a rotation to go around Mercury only has 88 days in a year cause its closer but since were farther we have 365 days in a year
What causes the planet's that are closer to the sun to move faster?
it's gravity
When two artificial satellite revolve around the earth the one's closer and the one's further. which one revolve the earth with higher speed?
The one that is closer will move at a higher speed. The same happens, for example, with planets revolving around the Sun - the planets closer to the Sun move faster.
Why does it take planets longer to go round the sun?
Gravity. The closer a planet is to the sun, the faster it must move to keep from falling into the sun. So note; the closer in; the smaller the orbit AND the faster the speed.

What will be the motion of ring?
The particles in the rings around planets move according to Kepler's Third Law. In other words, the particles closer to the planet move faster than the particles further outside.
