GEO E111 Lecture Notes - Lecture 6: Meteoroid, Meteorite Find
Document Summary
Are small fragments of rocks left going around the sun when the solar system was formed. They sometimes collide with each other and planets due to jupiter"s gravitational pull causing them to move in erratic orbits. Heavenly bodies which appear to have a head and a long tail. The head is made of many particles of dust, rock and frozen gases. Their tail is made of gases and points away from the sun. Move around the sun in extremely long and oval orbits. Their orbits cross the earth"s orbits e. g. halley"s comet which appears after every 76 years. Small heavenly body which strays from its orbit in the solar system and enters the earth"s atmosphere at very high speed. A meteoroid which is burning out due to friction after entering the earth"s atmosphere. Remains of a meteoroid which have reached the earth"s surface or incompletely burnt up meteoroid. When they fall they sink into the ground forming craters.
