Perhaps a limited audience for this cartoon, as snottites are probably not common knowledge (it’s never a good start when you have to explain your cartoons, but I’m rather attached to it). I first heard of their existence by watching the Wonders of the Universe/Solar System documentaries by Prof Brian Cox.
So what do these little suckers looks like? Well, as you can imagine their name was inspired by their appearance – check out these snottite photos and for more info read the NASA website’s article.
