👉 In astronomy, a "saturnicentric" system is an astronomical model that places the Earth on its axis of rotation. This means that the Earth orbits around the Sun in a nearly circular orbit, rather than a more elliptical path like that of a planet. Saturn's orbit is approximately 93 million miles (150 million kilometers) from the Sun. To understand how this model works, you can think about it as if you were looking at the Earth from Saturn's perspective
