M37<\/b>\u00a0aussi appel\u00e9\u00a0NGC 2099<\/b>\u00a0est un\u00a0amas ouvert<\/a>4<\/a><\/sup>,<\/sup>2<\/a><\/sup>\u00a0situ\u00e9 dans la\u00a0constellation<\/a>\u00a0du\u00a0Cocher<\/a>. Il a \u00e9t\u00e9 d\u00e9couvert par l’astronome\u00a0sicilien<\/a>\u00a0Giovanni Battista Hodierna<\/a>\u00a0avant l’ann\u00e9e\u00a01654<\/a>.\u00a0Charles Messier<\/a>\u00a0a d\u00e9couvert ind\u00e9pendamment cet amas en 17641<\/a><\/sup>.<\/p>\n

<\/span>Caract\u00e9ristiques<\/span><\/h2>\n

Selon la\u00a0classification des amas ouverts<\/a>\u00a0de\u00a0Robert Trumpler<\/a>, cet amas renferme plus de 100 \u00e9toiles (lettre r) dont la concentration est moyenne (II) et dont les magnitudes se r\u00e9partissent sur un petit intervalle (le chiffre 1). M37 est situ\u00e9 \u00e0 environ\u00a01\u00a0383\u00a0pc<\/a><\/abbr>\u00a0(\u223c4\u00a0510\u00a0al<\/a><\/abbr>) du\u00a0syst\u00e8me solaire<\/a>\u00a0et les derni\u00e8res estimations donnent un \u00e2ge de 347 millions d’ann\u00e9es4<\/a><\/sup>. La taille apparente de l’amas est de 15,0\u00a0minutes d’arc<\/a>, ce qui, compte tenu de la distance, donne une taille r\u00e9elle maximale d’environ 19,7 ann\u00e9es-lumi\u00e8re.<\/p>\n<\/div><\/div><\/div>
