Explication du ph\u00e9nom\u00e8ne<\/span>\u00a0:<\/strong><\/span><\/p>\n

La Lune va passer dans l\u2019ombre de la Terre et se priver progressivement de la lumi\u00e8re du Soleil, jusqu\u2019\u00e0 l\u2019\u00e9clipse totale o\u00f9 les trois astres seront parfaitement align\u00e9s ou partielle selon l\u2019endroit de la terre o\u00f9 l\u2019on se trouve.<\/span><\/p>\n

Pourquoi la lune nous est-elle apparue si volumineuse et lumineuse<\/span>\u00a0?<\/strong><\/span><\/p>\n

Comme la lune tourne autour de la terre avec une orbite qui n\u2019est pas circulaire mais l\u00e9g\u00e8rement elliptique, la distance de la Terre \u00e0 la Lune varie entre 356\u00a0000\u00a0kilom\u00e8tres et 407\u00a0000\u00a0kilom\u00e8tres. Plus elle s\u2019approche de nous, et plus elle para\u00eet grosse, et quand son gros diam\u00e8tre co\u00efncide avec la pleine Lune on parle de SUPER LUNE<\/em><\/strong><\/span><\/p>\n

Concr\u00e8tement, l’astre sera le plus proche possible de la Terre et par illusion d’optique il para\u00eetra 14% plus grand que d’ordinaire et 30% plus lumineux.<\/span><\/p>\n

Pourquoi la lune est devenue rouge sang\u00a0? Appel\u00e9e aussi \u00ab\u00a0lune sanglante\u00a0\u00bb<\/strong><\/span><\/span><\/p>\n

Lors de l\u2019\u00e9clipse, la lune est priv\u00e9e de la lumi\u00e8re du soleil, on s\u2019attendrait alors \u00e0 ce que la Lune devienne noire\u2026 mais c\u2019est une cape orange sombre qu\u2019elle va rev\u00eatir. D\u2019o\u00f9 viennent les quelques rayons de lumi\u00e8res qui l\u2019\u00e9clairent alors\u00a0? Toujours du Soleil, mais d\u00e9vi\u00e9s par la Terre et filtr\u00e9s \u00e0 travers son atmosph\u00e8re.<\/span><\/p>\n
