Yes, there was a asteroid storm a couple of weeks ago
Numerous asteroids are in constant motion around the earth, infinitely tracing their orbits. Occasionally some will collide or break down and fall as bits of meteor to Earth.
Asteroids can fall on any planet (or moon).
The asteroids that strike earth's surface do not fall from orbit. Asteroids have fairly small masses, so their orbits are easily altered by interactions with other objects. Sometimes the orbit of an asteroid is changed such that its orbit intersects Earth's orbit. If the timing works out so that the asteroid reaches the point of interestion at the same time as Earth does, then a collision will result.
I think it might be because it can fall down into the earth one day.
I think they're simply called asteroids if that's what you're asking. You may be thinking of meteors though. Meteors when they're in space. Meteorites when they fall to Earth.
In the beginning of the history of the solar system the Earth was bombarded frequently by asteroids. Now the frequency has diminished significantly but still many tons of "space rocks" fall into the Earth's atmosphere each year some of these hit the ground.
The densest form of interplanetary debris are asteroids. Asteroids are basically thick rocks that come together from the interplanetary dust and debris that sometimes fall to Earth.
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
asteroids vary in size from rock size to earth size and bigger.
Yes they do.
It is possible for comets and asteroids to hit Earth, but they are extremely rare events.
Comets and asteroids are made of chunks of space rocks and dust. Meteorites are space rocks that are captured by the earth's gravity and fall to earth.
