Moonlet
From Wikipedia, the free encyclopedia
Moonlet is an informal term for a particularly small natural satellite. In astronomical literature, it has been used in at least two situations:
- A belt of objects embedded in a planetary ring, as in Saturn's A Ring or S/2009 S 1 in the B Ring ("propeller" moonlets)[1][2] or in Saturn's F Ring.[3]
- Occasionally for asteroid moons, such as the moons of 87 Sylvia.[4]
