If space junk means man-made objects, very few have left Earth-orbit. Of the ones in Earth-orbit many crash each year but the vast majority burn up because of friction as they come at high speed through the upper atmosphere.
If a planet doesn't follow its orbital path, then it may crash into other planets, moons and/or other object floating around in space.
Space shuttles are not designed to go to other planets, they stay in a near earth orbit, orbiting earth several times in a mission before returning back to earth. They don't really go far from our planet.
the Hubble space telescope
Some objects in outer space that can damage the earth could be the following: Asteroids Sun Particles Rocks from other planets Space bombs Fire Other objects flying around in space
Because Earth's gravity is stronger the farther in through the atmosphere you go. Out of the atmosphere in space there is no gravity except on other planets.
The moon and other planets and their satellites are held in space by the force of gravity from other planets and satellites. If the moon tried to drift off into space, gravitational forces from the Earth will keep it from floating away. It doesn't crash into the Earth because planets and moons pull AGAINST each other and keep each other from drifting away.* * * * *Only partly true.The moon does not float away because of the action of earth's gravity - whether you view this as a force or a distirtion of space-time in the moon's path.The moon does not crash into the earth, not because of other planets or satellites, but because of the momentum of its orbit around the earth.
== == This is what keeps Earth in place. If there was no gravitational feilds, the Earth would crash into other planets, and space objects. It pushes the moon away from the Earth and the sun pushes the Earth away. Like repelling magnets. == == == == == == == ==

Each planet stays in it own orbit or path as it circles the sun. The orbits are very very very far apart. the planets never move out of their orbits so they never crash into each other. space probes that go from earth to Venus and Mars our closet neighbor planets have to travel for several months. space probes that go to the farther planets have to travel for years. :) Answer from my first book about space, a question and answer book.<3

Other planets appear shiny from Earth for the same reason the moon does, we see the other planets' reflected sunlight.
no because there is no oxogen in space
that the earth was in the middle of the universe
Space was born with planets we don't live in like Mars, Sun, And Jupiter. It need other planets to help keep Space alive forever. It can't just have Earth.
Because the suns orbit holds the earth and all of the other planets in place.
To explore areas outside of earth and to work on space travel so we canone daycolonize other planets.
Yes!! Rocks and other space objects crash into them all the time!!
