 Meteor Streams
Meteor streams are groups of meteoroids
originating typically from dust grains ejected from comets.
These small dust grains are distributed along the parent
comet's orbit concentrated close to the comet nucleus
with fewer grains farther away from the nucleus.
Every time the Earth passes through such a stream of dust particles
(i.e. meteor stream), we experience what is known as a meteor shower.
Of particular interest to solar system dynamics is the association of a
parent (source) body with a specific meteor stream.
The following table lists known meteor streams
in chronological order of peak activity.
In addition to the name of the meteor stream and time of peak activity,
the associated parent body (where known) is also shown.
