Bien que la chaleur estivale puisse nous faire croire le contraire, c’est bien d\u00e9but juillet que la distance entre la Terre et le Soleil est la plus grande.\u00a0<\/strong><\/p>\n

La Terre, comme toutes les plan\u00e8tes, circule autour du Soleil <\/a>sur une orbite elliptique : en 2015 la distance entre ces deux astres \u00e9tait la plus petite (p\u00e9rih\u00e9lie) le 4 janvier (un peu plus de 147 millions de km) et la plus grande (aph\u00e9lie) le 6 juillet (un peu plus de 152 millions de km).<\/p>\n

\"aph\u00e9lie\"<\/a><\/p>\n

Cette diff\u00e9rence de 5 millions de km est perceptible quand on compare deux images du Soleil prises \u00e0 ces deux dates extr\u00eames, comparaison qui n’est possible qu’en utilisant la m\u00eame focale pour les deux prises de vues.<\/p>\n

Le diam\u00e8tre apparent du Soleil est l\u00e9g\u00e8rement plus petit en juillet qu’en janvier comme le prouve le montage ci-dessus, r\u00e9alis\u00e9 par l’astrophotographe Giuseppe Petricca<\/a> qui observe depuis Pise en Italie.<\/p>\n

Notez \u00e0 ces deux dates la pr\u00e9sence de jolis groupes de taches solaires<\/a> : en janvier il s’agissait de AR 2253 (au centre du disque), en juillet c’est le groupe AR 2381 dont on peut suivre actuellement le d\u00e9veloppement sur les images du satellite SOHO<\/a>.<\/p>\n

La variation de distance du Soleil <\/a>n’a aucune incidence sur le chauffage de notre plan\u00e8te ; s’il fait plus chaud chez nous en \u00e9t\u00e9 c’est simplement parce que l’h\u00e9misph\u00e8re nord re\u00e7oit plus d’\u00e9nergie solaire en raison de l’inclinaison de l’axe de rotation terrestre.<\/p>\n","protected":false},"excerpt":{"rendered":"
