It was discovered by the Cassini Imaging Team in images taken on May 30, 2007. Once the discovery was made, a search of older Cassini images revealed this small satellite in observations from as far back as June 2004. It was first announced on July 18, 2007.
Anthe is visibly affected by a perturbing 10:11 mean-longitude resonance with the much larger Mimas. This causes its osculating orbital elements to vary with an amplitude of about 20 km in semi-major axis on a timescale of about 2 Earth years. The close proximity to the orbits of Pallene and Methone suggests that these moons may form a dynamical family.
Material blasted off Anthe by micrometeoroid impacts is believed to the source of the Anthe Ring Arc, a faint partial ring about Saturn co-orbital with the moon first detected in June 2007.
