Radiant (meteor shower)

The radiant or apparent radiant of a meteor shower is the celestial point in the sky from which (from the point of view of a terrestrial observer) the paths of meteors appear to originate. The Perseids, for example, are meteors which appear to come from a point within the constellation of Perseus. A meteor that does not point back to the known radiant for a given shower is known as a sporadic and is not considered part of that shower.
