| | meteor shower |
 | | Meteors seen to fan out from a single point in the sky, known as the radiant, in a burst of activity lasting for several hours or days. |
 | | A meteor shower consists of dusty debris, spread out along part of the orbit of a parent body, usually a comet, which Earth intersects at the time each year. |
 | | The Leonids are famous for this, normally putting on a modest annual show of up to 15 meteors per hour but, every 33 years or so, when the parent comet, Tempel-Tuttle, is at perihelion and in Earth's neighborhood, capable of staging a meteor storm. |
