NASA’s cassini spacecraft has found within saturn’s g ring an embedded moonlet that appears as a faint, moving pinprick of light. scientists believe it is a main source of the g ring and its single ring arc.
cassini imaging scientists analyzing images acquired over the course of about 600 days found the tiny moonlet, half a kilometer (about a third of a mile) across, embedded within a partial ring, or ring arc, previously found by cassini in saturn’s tenuous G ring.
