A second radar map looks at meteoroid speed. The red regions indicate a speed of 7.5 miles/s (12km/s), the green from 26 miles/s (42km/s) and the blue from 41 miles/s (66km/s)
Maps produced using the space agency’s Asgard program which tracks an estimated 4,000-5,000 meteoroids a day
WHICH ROCK IS WHICH?
An asteroid is a large chunk of rock left over from collisions or the early solar system.
Most are located between Mars and Jupiter in the Main Belt.
A comet is a rock covered in ice, methane and other compounds. Their orbits take them much further out of the solar system.
A meteor is what we call a flash of light in the atmosphere when debris burns up.
This debris itself is known as a meteoroid. Most are so small they are vapourised in the atmosphere.
If any of this meteoroid makes it to Earth, it is called a meteorite
Meteors, meteoroids and meteorites normally originate from asteroids and comets.
