Messier 44<\/strong> ou l\u2019amas de la cr\u00e8che, ou Praesepe, c\u00e9l\u00e8bre amas ouvert dans le Cancer, plus ancien que les Pl\u00e9iades.
A 182 Parsecs de nous, sa taille angulaire est de 12 ann\u00e9es-lumi\u00e8re.
Les Grecs distinguaient parmi les 1000 \u00e9toiles qui le composent \u00ab l\u2019\u00e2ne du sud \u00bb et \u00ab l\u2019\u00e2ne du nord \u00bb, chevauch\u00e9s respectivement par Dionysos et Sil\u00e8ne. Galil\u00e9e, avant Messier, y r\u00e9solut 40 \u00e9toiles.
On y a localis\u00e9 11 naines blanches, que j\u2019ai mises en \u00e9vidence dans le diagramme HR g\u00e9n\u00e9r\u00e9 \u00e0 partir de ma photo. Une tr\u00e8s grande partie des autres \u00e9toiles suit la s\u00e9quence principale, comme vous pouvez le voir. Autour de deux de ces Soleils gravitent deux Jupiters chauds.
Enfin, c\u2019est aussi et surtout l\u2019amas de la ruche, et \u00e0 ce titre l\u2019un des symboles de l\u2019Utah.<\/p>\n\n\n\n
