To be in a perfect orbit around the Sun, maintaining always the same distance, at a specific distance a planet would need a very specific speed. Since it is unlikely that it just happens to have the correct speed, it will move around the Sun in an ellipse instead.

Do planets collide when the distance of the planets from the sun change?

The distance of the planets from the sun does not change because of the gravity surrounding each planet is pulling them into continuous orbit.


Is the distance between the planets and sun changing?

Yes, very slowly the planets shift, and move, away, and closer to the sun. But we will never see any massive change soon.


Distance from earth the closest to farthest planets?

Neptune is the remotest of the eight planets, and its distance is 30 astronomical units, which means its distance from the Sun is 30 times the Earth's distance from the Sun.


How does the planets distance from the sun affect its conditions?

The farther away from the sun the planet is, the more space it has to cover. Therefore, the planets distance from the sun whereas, if i am half the distance from Earth/Sun, that planet will get more energy. But if I am twice the distance from Earth/Sun, I will receive less energy.


What do the length of the planets year and its distance from the sun have in common?

There is a relationship between the planets distance from the sun and the time taken for one orbit (planets year), described in Keplers third law. The square root of the time taken to orbit the sun is proportional to the cube of the average distance between the sun.


How does the distance between the inner planets differ from the distance between the outer planets?

As the names suggest, the inner planets are closer to the Sun than the outer planets.


What is the relation of the planet's temperature to it's distance?

if you are asking "what is the relation of the planet's temperature to it's distance from the sun" then the answer is: Planets closer to the sun tend to be warmer than planets further from the sun.


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


How does the sun have gravity?

The sun has all the gravity to keep the planets a certain distance from the sun.
