Meteor shower is an event that occurs when tiny particles of stones that are of the size of a golf ball or baseball hits the earth's atmosphere.
As the particles enters the earth's atmosphere, they create friction through rubbing against the particles of the air. This eventually causes the particles to heat up leading to the formation of a fireball.
Meteor shower usually occurs between midnight and the very early hours of the morning.
