Explanation:
Detailed explanation-1: -Think of them as “space rocks.” When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
Detailed explanation-2: -Some meteoroids are fragments from bodies such as Mars or the Moon, that have been thrown into space by an impact. Meteoroids travel around the Sun in a variety of orbits and at various velocities. The fastest move at about 42 km/s (94, 000 mph) through space in the vicinity of Earth’s orbit.
