The Other Planets Nearly Fit Between Earth and the Moon

The average distance between Earth and the Moon is about 384,000 km. That’s nearly enough to line up every other planet in the solar system side by side: their combined diameters come to roughly 380,000 to 388,000 km, depending on how you measure the gas giants. Jupiter, Saturn, Uranus, and Neptune are enormous, but space itself is even bigger—proving once again that distances in our cosmic neighborhood are easy to underestimate.
