== Što uzrokuje meteorske pljuskove ==
Kako se približavanjem kometa Suncu povećava temperatura na njegovoj površini, led se počinje topiti i sa topljenjem leda se komet počinje raspadati. Iza njega ostaje trag prašine i komadića stijena. Ako se kometova orbita presječe sa Zemljinom i na Zemljinoj stazi ostavi prašine, Zemlja će svake godine ulijetati u taj oblak prašine. Zbog trenja zraka u atmosferi, čestice prašine se zapale i u atmosferi nakratko ostave sjajan trag - nastaje meteor.

Najpoznatiji meteorski potok su Perzeidi ili Suze svetog Lovre. Vidljivi su u noći sa 12. na 13. kolovoza.

== Meteor Showers Originate From Fixed Points in the Sky ==
Because meteor shower particles are all traveling in parallel paths, and at the same velocity, they will all appear to radiate from a single point in the sky to an observer below. This [[radiant (meteor shower)|radiant]] point is caused by the effect of [[Perspective (graphical)|perspective]], similar to railroad tracks converging at a single vanishing point on the horizon when viewed from the middle of the tracks. Meteor showers are almost always named after the constellation from which they appear to originate.
 
==Famous Meteor Showers==
 
The most visible meteor shower in most years are the [[Perseids]], which peak on August 12th of each year.
 
==Extraterrestrial Meteor Showers ==
 
Any other solar system body with a reasonably transparent atmosphere can also have meteor showers. For instance, Mars is known to have meteor showers, although these are different from the ones seen on Earth because the different orbits of Mars and Earth intersect orbits of comets in different ways. On [[March 7]], [[2004]], the panoramic camera on [[Mars Exploration Rover]] ''[[Spirit (rover)|Spirit]]'' recorded a streak which is now believed to have been caused by a meteor from a Martian meteor shower associated with comet [[114P/Wiseman-Skiff]]. A strong display from this shower is expected on [[December 20]] [[2007]], although it is unlikely that ''Spirit'' or ''[[Opportunity (rover)|Opportunity]]'' will still be operational at that time to observe it.
