Le\u00a0triplet du Lion<\/b>\u00a0(aussi appel\u00e9 le\u00a0groupe de M66<\/b>) est un petit\u00a0groupe de galaxies<\/a>1<\/a><\/sup>\u00a0situ\u00e9 \u00e0 environ\u00a035 millions<\/span>\u00a0d’ann\u00e9es-lumi\u00e8re<\/a>\u00a0dans le\u00a0constellation<\/a>\u00a0du\u00a0Lion<\/a>. Cet amas regroupe les\u00a0galaxies spirales<\/a>\u00a0M65<\/a>,\u00a0M66<\/a>, et\u00a0NGC 3628<\/a>\u00a0, commun\u00e9ment appel\u00e9e \u00ab\u00a0la galaxie du Hamburger\u00a0\u00bb.<\/p>\n

Quelques sources indiquent qu’une ou deux autres galaxies proches, telle\u00a0NGC 3593<\/a>, pourraient faire partie de ce groupe4<\/a><\/sup>.<\/p>\n

Groupe de galaxies proches<\/span>[<\/span>modifier<\/a>\u00a0|\u00a0<\/span>modifier le code<\/a>]<\/span><\/span><\/h2>\n

Le\u00a0groupe de M96<\/a>\u00a0est assez proche de ce groupe du Triplet5<\/a><\/sup>. Ces deux groupes pourraient \u00eatre une partie d’un bien plus grand groupe5<\/a><\/sup>, certaines simulations tendent \u00e0 prouver que le Triplet du lion fait partie du groupe de M966<\/a><\/sup>.<\/p>\n<\/div><\/div><\/div>
