Les anneaux de Saturne,
découverts en 1655 par l'astronome hollandais Christiaan
Huygens, entourent la planète dans son plan équatorial
et s'étendent à plus de 300 000 km du centre de l'astre.
Ce système d'anneaux a une épaisseur inférieure
à 1 km.
Au cours de la rotation de Saturne
autour du Soleil, les anneaux nous apparaissent sous un angle variable
depuis la Terre. Tour à tour, ses faces sont éclairées
par le Soleil, mais à cause de l'excentricité de l'orbite
de la planète, la face Nord est éclairée pendant
15 ans et 9 mois, tandis que la face Sud ne l'est que pendant 13
ans et 8 mois.
Aux environs des équinoxes
saturniens, les anneaux se trouvent alors dans le même plan
que le Soleil, et ceux-ci sont éclairés très
faiblement, disparaissant même pour l'observateur terrestre.
Lorsqu'à son tour, la Terre traverse le plan des anneaux,
Saturne paraît dépourvue d'anneaux pendant plusieurs
mois.
