Meteor shower on chart. Because meteor shower particles are on parallel paths, at the same velocity, they appear to an observer to come from a single point in the sky.
A meteor shower is an event when many meteors seem to come from one point in the night sky. These meteors are caused by meteoroids entering Earth's atmosphere at extremely high speeds on parallel paths. Most meteors are smaller than a grain of sand, so almost all of them burn up and never hit the Earth's surface.
