All about Meteorites
Topic 4
When a meteorite enters the upper atmosphere of Earth, it is travelling very fast at a speed of approximately 48280kph. When it enters the atmosphere the air in front of it is compressed. When gas is compressed, its temperature rises. The hot air heats the leading edge of the meteorite as high as 1,650 Degrees C .
Small bits of space junk burns on re-entry but some survives and lands on Earth once a week.
