Rings and moons

Definition

Rings and moons are the matter that orbit a celestial body other than a star. Rings are a collection of dust or small particles that form into a flat disk. Moons, or natural satellites, are much larger single bodies. Large moons can themselves support rings.

    Cassini’s camera observed Titan from orbit at different angles (0–166°) and found that the planet looks brighter towards the night than at midday. This effect, linked to the scattering properties of Titanian haze, can also be present in exoplanets.
