Document Summary
1086g origin and geology of the solar system: introduction. Near-earth objects (neos) are objects in solar system, whose orbits have been brought into proximity with the earth. Near-earth objects include thousands of near-earth asteroids, spacecraft, meteoroids and comets. Thousands of asteroids that have fallen on earth were collected and catalogued. Near-earth comets come from the outer region of our solar system that was probably derived beyond the orbit of neptune, the kuiper belt. As a result, comets that crosses earth"s orbit must have very high elliptical orbits in order to reach the earth due to their distance to our planet. It is very important to investigate and pay attention to those extraterritorial objects since sometimes their impact on earth can have drastic effect upon colliding. Asteroids with diameter of less than 10 meters enter. Earth"s atmosphere with little energy, only approximated to be the equivalent of the little.
