Compare Planet Sizes
This interactive lets you compare the sizes of planets in our Solar System. It does NOT show where they are in the Solar system or how far apart they are from each other.
Move the slider to zoom in and out. You can hide the planet labels text and/or the distance scales if you want to.
(Note: If you cannot see the animation below, or it is not working properly, you may need to download the latest Flash player.)
