Over the weekend I fell into a bit of a science-fiction/science rabbithole. You know, one of those when you click on ONE Youtube video and suddenly the whole Sunday afternoon is gone and your algorithm is all messed up. 

Anyway, obviously there's tons of fascinating stuff about space and science and all that. Too much, really. 

But one fun fact has stuck in my brain: All the other planets in the Solar System could fit between Earth and our Moon. 

It seems crazy to think, considering some of the basic 'facts' about the Solar System that we probably learnt growing up. Jupiter is gigantic, Saturn is huge, Earth is but so small. And the Moon! Our Moon! It's just there, you can literally see it in the sky every night. 

But the numbers are the numbers. Earth to the Moon is about 400,000km. The combined diameters of Mercury (4,879km), Venus (12,104km), Mars (6,779km), Jupiter (142,800km), Saturn (120,500km), Uranus (51,118km) and Neptune (49,528km) adds up to 387,708km. Yep, less than the distance between Earth to the Moon. And we set foot on the Moon 1969!

It just goes to show just how vast space is, and equally how empty it is as well (we're at this point not going to delve into dark matter). 

Crazy, huh. Science.
