Ces com\u00e8tes laissent de nombreuses tra\u00een\u00e9es de gaz et de poussi\u00e8re derri\u00e8re elles.<\/p>\n<\/div>\n<p>Les grains de poussi\u00e8re, de la taille d'un grain de sable, viennent parfois percuter la fine couche d'air qui entoure la Terre, appel\u00e9e atmosph\u00e8re, o\u00f9 ils s'\u00e9chauffent tr\u00e8s rapidement. En se consumant, ces grains de poussi\u00e8re laissent des tra\u00een\u00e9es lumineuses dans le ciel nocturne. Ces tra\u00een\u00e9es sont appel\u00e9es \u2018 m\u00e9t\u00e9ores \u2019, souvent surnomm\u00e9es \u2018 \u00e9toiles filantes \u2019 ou \u00ab \u00e9toiles tombantes \u00bb.<\/p>\n<p>Par nuit claire, si vous observez le ciel assez longtemps, vous verrez l'une de ces \u00e9toiles filantes. A certaines \u00e9poques de l\u2019ann\u00e9e, la Terre traverse la queue d'une com\u00e8te. Le nombre d'\u00e9toiles filantes peut alors atteindre une centaine par heure.<\/p>\n<p>En de rares occasions, des pluies de m\u00e9t\u00e9ores ont \u00e9clair\u00e9 le ciel tout entier. Tous ceux qui ont vu la pluie des L\u00e9onides de 1966 ont observ\u00e9, \u00e0 leur plus grande surprise, 40 \u00e9toiles filantes par seconde!<\/p>\n<nav class=\"related\" aria-label=\"\u00c0 lire \u00e9galement\">\n<h2 class=\"related__heading\">\u00c0 lire \u00e9galement<\/h2>\n<div class=\"grid related__grid\">\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/fr\/stjerneskud\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">danois<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/fr\/vallende_sterren\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">n\u00e9erlandais<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/fr\/sternschnuppen\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">Allemand<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/fr\/stjerneskudd\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">norv\u00e9gien<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/fr\/spadajace_gwiazdy\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">polonais<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/fr\/fallande_stjaernor\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">su\u00e9dois<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<\/div>\n<\/nav>","protected":false},"excerpt":{"rendered":"<p>There are several hundred comets that spend most of their lives among the planets of the inner Solar System.
