If you shrank the sun down to the size of a ping pong ball, the earth would be the size of a very fine grain of sand about three yards away.

Jupiter would be the size of a small pea about 15 yards away.

Pluto would be just over 100 yards away, and it would be so small you'd need a microscope to see it.

At this scale, light travels about a foot a minute, and the nearest star is... 400 miles away.

It's a big universe. And it's mostly empty space.
