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.
