Why is one year shorter on planets close to the sun and longer on outer planets like Uranus?

It comes down to 3 main factors - associated with centrifugal/centripetal force plus gravity:
Firstly, is simply the much smaller path required for a planet closer to the sun to travel in its orbit of the sun. Naturally, this will mean that (assuming the speeds of travel through space to be the same),the lesser distance to cover will result in a shorter year.
Second factor: In order to prevent gravity from pulling a body closer to the sun in a collision course, the outward force/momentum propelling it away must be more marked.
Hence the revolving object must travel faster through the air in a more outward direction as if 'away' from the object it is orbiting.
Third factor: The size of the planet will also affect the overall 'drawing power' between the 2 heavenly bodies. If Both objects were large, the overall gravity would cause that they close in on one another.
If the planets close in were as large as Uranus, there would be certain collision unless the velocity through space of the large planet was many times that of a smaller planet at such distance from the sun. If Uranus replaced Mercury, for instance, the planet would have to travel at some speed many times faster than that of the speeds of those smaller planets in closer to the sun, and a large planet that close might affect the stability of the sun's traverse through space.

How Uranus' axis of rotation differs from those of other planets?
Uranus' axis of rotation is different in that it rotates at close to a 90 degree angle. This makes it rotate nearly parallel to the plane of the Solar System.
What are the similarities of Uranus and Neptune?
bolth planets are gas planets and close to the same distance from the sun
Which 2 planets is close to the same size?
Venus and Earth are similar in size, also Uranus and Neptune are pretty similar in size.
What ryhmes with Uranus?
There are no rhymes of Uranus. Close ones are acinus, agnus, agonus.
What is uranus's orbit shape?
All planets are very close to sphere shaped. They all have a little bulge around the equator where the spinning stretches them. This answer was very useless.
What planets are close to Saturn?
Jupiter and Uranus.....Well that's what Saturn is close to!
How Uranus' axis of rotation differs from those of other planets?
Uranus' axis of rotation is different in that it rotates at close to a 90 degree angle. This makes it rotate nearly parallel to the plane of the Solar System.
What outer planets are about the same diameter?
neptune and uranus r pretty close
What are the similarities of Uranus and Neptune?
bolth planets are gas planets and close to the same distance from the sun
Which planets have similar diameter?
The Earth and Venus are pretty close to being the same size (about 5% difference), and Uranus and Neptune are also pretty close to the same size (about 4% difference). All of the other planets are different.
Which 2 planets is close to the same size?
Venus and Earth are similar in size, also Uranus and Neptune are pretty similar in size.
Which planets are larger then Earth?
In our solar system there are 4 planets larger than Earth, which are collectively known as the gas giants; these are Jupiter, Saturn, Uranus, and Neptune. There are many other planets larger than Earth in other solar systems as well.
How many planets are bigger than Earth?
Pluto is not a planet so that would be Mercury is 13.72% smaller. Venus is 0.23% smaller. Mars is 9.42% smaller. So that means 3 planets are smaller than Earth.
Why are Russia's growing seasons considerably shorter than the US?
longer winters and close to the north pole
Why were Uranus' rings were first spotted from the Earth during an eclipse of a star by Uranus?
It would have caused a much shorter disappearance and reappearance of the star along with the main long eclipse, which would have been a good indicator that there was something else close to Uranus. Further examination would have led to the discovery of the rings.
What two planets are close in size?
Venus and Earth are similar in size. Uranus and Neptune are also of a similar size, but both much larger than Earth and Venus.
How close can people get to Neptune?
I am not sure how close people can get, but there is an asteroid belt separating the inner planets (Mercury, Venus, Earth, and Mars) from the outer planets (Jupiter, Satuen, Uranus, Neptune). We haven't even tried human travel to Mars or Venus so I am guessing noot very far.
