why does the earth not collide with the other planets while revolving around the sun?

Answer 1

Each planet is in its own orbit around the Sun, and each planet is a different distance from the Sun. The nearest planet to us is Venus, and it's millions of miles away.

You can visit NASA's solar system exploration page to learn more about the Sun and the planets in our solar system: http://solarsystem.nasa.gov/index.cfm

I hope this helps.

Answer 2

Each planet has a different mass and orbits the sun at a different velocity. This, combined with centrifugal force, makes the planets move into orbits at specific distances, which, except in the case of Pluto (no matter what the astronomers say, most people will always think of it as a planet) and Neptune, never cross. If a planet hit, say, a comet with enough force to make it slow down in its orbit, it could theoretically drift toward the sun and hit another planet, but the chances of this happening are almost nonexistant.

Answer 3

Their orbits don't cross at all. It's like each one has its own lane on a highway and they never change lanes.

Pluto's orbit brings it closer to the sun than Neptune's from time to time, but even these orbits do not cross. Why? Because space is 3-dimensional, and at the points where Pluto's orbit is the same distance from the sun as Neptune's, Pluto is either above or below Neptune. Pluto's orbit is tilted a lot from the 8 planets' orbits. So even those two bodies (I want to call Pluto a planet, damnit!) will never collide either.

Answer 4

Because all the planets are orbiting the Sun at different distances, and they remain in their orbits. The orbits do not cross (except Pluto and Neptune, but that doesn't happen very often since they are so far apart).

Answer 5

With all due respect Sir, you need to do a little research about the distances involved between the Sun and the various planets. Once you have found these distances I think you will understand the obvious answer to your question; they are to far apart.

Answer 6

gravity from the sun holds each one of them in their own orbit

Answer 7

Nasa website is great for explanation.
study an atom-it moves also.

Answer 8

Please do an internet search on "solar system" or "orbits of planets."
