What happens to the speed of a planets as you get closer to the sun?

Yes. That'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.

from the central body, and faster when it's nearer to the central body.
Comets do it, the Earth does it, the Moon does it, asteroids do it, the
International Space Station does it, the Apollo command modules and the
Space Shuttles did it, and astronauts on space-walks do it.
The reason is: That's the way gravity works. If you take Newton's formula for
gravitational force, and you have enough geometry and calculus to play around
with the formula and MASH it into different shapes and forms, then all of Kepler's
laws of planetary motion fall right out of the math. The statement about faster,
slower, nearer, and farther is Kepler's third law.

An alternative explanation is that when the planet moves closer to the Sun it gives up potential energy from the gravitational field which is converted to kinetic energy. With more kinetic energy it moves faster.
Take your pick.

Wiki User
∙ 15y agoIt speeds up at it gets closer to the sun, then slows down again as it leaves.
Wiki User
∙ 13y agoBecause of the effect of the Sun's gravitational pull.

What happens to the speed of planets orbiting the sun as you get closer to the sun?
they get faster
Why do the 4 inner planets revolve around the sun at a faster speed?
Their closer to the sun.
What happens if the planets stops orbiting the sun?
The planets will fall into the sun and get destroyed.
What happens to a plant's speed when it gets closer to the sun?
tempatures start to rise . and alot of diffrent things lol (:
What happens to earths oribit speed as it gets closer to the sun?
According to Kepler's Law the closer you are to the Sun the faster you travel. You kind of whip around it. Imagine running and reaching out to a pole and it whips you around it.
What happens to the speed of planets orbiting the sun as you get closer to the sun?
they get faster
How does a planets distance from the sun affect the planets orbit speed?
the closer you are to the sun it affects the planets speed cause of the suns gravitational pull
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 do the 4 inner planets revolve around the sun at a faster speed?
Their 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
Does the speed of planetary orbits increase the closer the planet is to the sun?
Yes. Planets (and other things) orbit at a higher speed the closer they are to the object they are orbiting.
What happens to the earth orbit speed as it gets closer to the sun?
It increases.
Why inner planets are closer to the sun than outer planets?
They are closer to the sun because their orbits are smaller.
Why are Terrestrial planets closer to the sun then the Jovian planets?
Terrestrial planets are made of denser materials than Jovian planets. The planets were primarily formed from the left over disc of dust that orbited our sun when it first formed. The heavier elements were draw closer to the sun by gravity and the lighter ones flung further outward by their high orbital speed.
Is Uranus' speed less than or greater than Jupiter's speed?
Less. Uranus is further away from the Sun. In general, 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.
How many planets are closer to the Sun than Jupiter?
The planets closer to the Sun than Jupiter are: Mercury, Venus, Earth, and Mars. So, four planets are closer than Jupiter.
