Atlas is an inner satellite of Saturn. Atlas was discovered by Richard Terrile in 1980 (some time before November 12) from Voyager photos and was designated S/1980 S 28. In 1983 it was officially named after Atlas of Greek mythology, because it "holds the rings on its shoulders" like the Titan Atlas held the sky up above the Earth. It is also designated as Saturn XV. Atlas is the closest satellite to the sharp outer edge of the A ring, and was long thought to be a shepherd satellite for this ring. However, now it is known that the outer edge of the ring is instead maintained by a 7:6 orbital resonance with the larger but more distant moons Janus and Epimetheus. In 2004 a faint, thin ring, temporarily designated R/2004 S 1, was discovered within Atlas's orbit. High-resolution images taken in June 2005 by Cassini reveal a saucer-shaped moon with a large smooth equatorial ridge. The most likely explanation for this unusual and prominent structure is that ring material swept up by the moon accumulates on the moon, with a strong preference for the equator due to the ring's thinness. In fact, the size of the equatorial ridge is comparable with the expected size of Atlas's Roche lobe. This would mean that for any further particles attempting to accumulate on the equator, the centrifugal force overcomes Atlas's tiny gravity and they will be lost. Atlas is significantly perturbed by Prometheus and to a lesser degree by Pandora, leading to excursions in longitude of up to 600 km (~0.25°) away from the precessing keplerian orbit with a rough period of about 3 years. Since the orbits of Prometheus and Pandora are chaotic, it is suspected that Atlas's may be as well.

The proper name for the study of stars is astronomy. A person who studies stars is an astronomer.
Synonyms of astronomy are: stargazing, starwatching, radio astronomy, astrophysics, and space science.
Atlas is Greek, but he is not a god. He is a Titan.
An atlas is a research document of maps.
Atlas was son of Titan Iapetus and Oceania Clymene
Urania was a Muse goddess of astronomy. Atlas and Hermes are also astronomy gods.

Atlas is known for his strength, endurance, and resilience. He is often depicted as carrying the weight of the world on his shoulders, symbolizing his immense burden and responsibility. Additionally, Atlas is associated with navigation and astronomy, as he is said to have held up the celestial sphere.

Atlas was the Titan who supported the "celestial spheres" (planets) on his shoulders. Due to his involvement with astronomy, collections of maps were dedicated to him, and they became known as an Atlas. Regarding the moving company, they formed in 1948, and chose the Name Atlas Van Lines as a memorable name- and the catch phrase "We move the world for you."
