(Newser) – Scientists have discovered Saturn’s 60th moon, and are hinting that more could exist. In May, cameras aboard the Cassini spacecraft captured the “extremely faint object,” which scientists have officially designated a moon and tentatively named Frank. Composed mostly of ice and rock, Frank is about a mile wide and orbits between two other Saturnian moons, Methone and Pallene.

Scientists say the close proximity between Frank and its Saturnian cousins suggests the existence of a network of more hidden moons. Before the Cassini mission’s launch in 1997, astronomers only knew about 18 of Saturn’s satellites and have since uncovered 42 more. Frank will receive a new, official name from the International Astronomical Union.
