The Moon is our nearest celestial neighbor, but it’s tempting to think it’s much closer to Earth than it really is. The Moon has an average distance from Earth of 384,399 kilometers (or 238,854 miles if you prefer). We know that’s far, but how far is that really? It turns out it’s far enough to fit every other planet in the solar system with room to spare. Check it out:
I spotted this image on Twitter and thought it was a perfect illustration of the actual distance between the Earth and the Moon. But even then I needed a double-check so I went to Wikipedia, found the equatorial diameter of each of the planets and added them up. Sure enough, they came out to less than the average Earth-Moon distance:

As you can see, the average distance (or semi-major axis) between the Earth and Moon can accommodate all of the planets with room to spare! But perhaps the most dramatic example of the actual distance to the Moon is to simply just show it to scale:
Space is big. It’s really, really big. So big that it’s hard to not end this post with a quote from Douglas Adams:
Space is big. Really big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.
