This interactive Earth–Moon distance scale model shows Earth (left) and Moon (right) at true relative size, and the range of their distance. Adjust Moon’s diameter in pixels; Earth scales automatically.
Interactive scale models that let you explore real astronomical distances and object sizes.
Adjust the Moon’s diameter (in pixels). The other body size and the distance update live using real ratios. Drag to pan, or scroll to move around.
Tip: Large Moon sizes make the bodies and distance enormous — use the jump buttons.
