The latest thinking on this subject is as follows: Not all small and sundry asteroids can be stopped from hitting the earth. Those asteroids whose paths and trajectory are fairly known along with their periodicity can be nudged from a collision course to earth by sending a rocket or spacecraft. The proximity of the rocket or spacecraft itself is expected to change the trajectory of the asteroid (in a controlled and calculated manner.) In years to come, science may come up with other additions to this basic concept to successfully deviate the asteroid from its collision course to the earth.
What else can I help you with?
What prevents most small meteoroids from hitting Earth's surface?
the o zone
What prevents most asteroids comets and meteoroids from colliding with the earth?
Hopefully, they burn up on entering our atmosphere, due to friction with the air.
What are facts about Apollo asteroids?
Apollo asteroids are a group of near-Earth asteroids with orbits that intersect with Earth's orbit. They are named after the first asteroid of this group discovered, 1862 Apollo. Some Apollo asteroids are classified as potentially hazardous asteroids due to their close approach to Earth.
Which of these hit the earth comets or asteroids?
It is possible for comets and asteroids to hit Earth, but they are extremely rare events.
What are the names of the asteroids that cross Earth's orbit and Jupiter's orbit?
Main Belt asteroids -- a band of asteroids located in the "missing planet" gap between Mars and Jupiter. None of these are economically attractive in a near term program because they are too far from Earth.Amor asteroids -- asteroids whose orbits approach but do not cross Earth orbit, and whose orbits are further from the Sun than Earth's orbit (i.e., "outside-t" Earth orbit). Many have orbits which reside entirely between Earth and Mars. Some of these are economically attractive in the near term.Apollo asteroids -- asteroids whose orbits cross Earth's orbit. Apollo asteroids spend most of their time outside Earth orbit. Many of these are economically attractive in the near term.Aten asteroids -- asteroids whose orbits cross Earth's orbit. Unlike Apollos, Atens spend most of their time inside Earth orbit. A large percentage of known Atens are economically attractive in the near term.
What prevents most charge particles from the Sun from hitting Earth?

What effect did asteroids hitting the earth have?
All the way from forming the moon to pretty lights in the sky.

How can you stop an asteroid from hitting earth?
Small asteroids can be deflected by explosives (ordinary or nuclear) if they are far enough away. The problem is getting the explosives there. Asteroids travel at orbital speeds of thousands of kilometers an hour, and a large rocket would be required to reach the asteroid and match its speed, so that it could rendezvous and detonate. Hitting an asteroid with a head-on shot would be extremely difficult if not impossible, and could result in a shower of smaller pieces hitting the Earth.
What are the group of asteroids that may occasionally cross 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.
What are facts about Apollo asteroids?
Apollo asteroids are a group of near-Earth asteroids with orbits that intersect with Earth's orbit. They are named after the first asteroid of this group discovered, 1862 Apollo. Some Apollo asteroids are classified as potentially hazardous asteroids due to their close approach to Earth.
Are asteroids larger then earth?
asteroids vary in size from rock size to earth size and bigger.

Is Costa Rica safe from asteroids?
No. Asteroids can hit anywhere on earth.

How does air pressure effect the earth?
Air pressure is a atmospheric pressure. Air pressure creates: 1. Different climate 2. Creation of rain 3. Creation of wind 4. It prevents small asteroids to come to the earth
