Saturn at closer distances
Saturn is the object most people picture when they imagine a planet replacing the Moon, and the comparison holds up: the globe alone spans tens of full Moons at that distance, and the ring system reaches considerably further. Perigee renders the globe at its calculated angular size, and draws the rings to the same geometry.

How big does Saturn actually look from Earth?
At 8 AU, Saturn spans 0.01° across your sky — a small fraction of the width of the full Moon. Light crosses that gap in 66.4 minutes.
Saturn is a pale point. Its rings are far below what an unaided eye resolves.
How big would Saturn look if it replaced the Moon?
At 384,400 km, Saturn spans 17.2° across your sky — about 33 times the width of the full Moon. Light crosses that gap in 1.3 seconds.
The signature view: Saturn at the Moon's distance, rings reaching well past the globe.
How big would Saturn look from a hundredth of an astronomical unit?
At 1,495,979 km, Saturn spans 4.5° across your sky — about 8.6 times the width of the full Moon. Light crosses that gap in 5.0 seconds.
The ring plane and the gap dividing it are unmistakable.
How big would Saturn look from a tenth of an astronomical unit?
At 14,959,787 km, Saturn spans 0.4° across your sky — about 0.86 times the width of the full Moon. Light crosses that gap in 49.9 seconds.
Closer to Earth than Mercury orbits the Sun.
How big would Saturn look at one astronomical unit?
At 149,597,871 km, Saturn spans 0.04° across your sky — a small fraction of the width of the full Moon. Light crosses that gap in 8.3 minutes.

What Perigee calculates and what it renders
The apparent size on this page is calculated from the published diameter and the distance you choose, using the same geometry the live scene uses. The lighting and surface treatment are an authored visualization.
