A Piece of the Solar System: This isn’t my usual sort of post. But lately my 6 year old kid has been into planets, and thanks to the many informative videos on YouTube, has been reciting various names and numbers about the many worlds in the Solar System. I decided to show him just how much smaller than the Earth some of those worlds are. Here’s what I made for him. It’s not exhaustive, but it gives a good idea of just how small Pluto is relative to, say, the Moon. The scale is ~2 km/pixel. (Images attributable to NASA or ESA).
