xkcd #3156: Planetary Rings

Title text:

If you don't know where you are on Earth, the angle of satellite dishes can help constrain your latitude. If some of them are pointing straight up, you're probably near the Equator, right under the ring.

It is comforting knowing that our planet is protected by a dense layer of floating garbage. πŸ«‘πŸš€πŸ—‘οΈ

Your use of the word "dense" there is a little misleading. At the default view the scale of each satelite pixel looks roughly 20km wide.

Indeed, that's a joke I'm always saying, that every sat is the size of rhode island

Well Rhode Island is famously tiny so I doubt it's a problem

Hah, if satellites were actually that large... It still wouldn't actually be a problem. It's really hard to grasp just how far things are apart up in geostationary orbit, there is a truly immense amount is space. There's plenty of elbow room for thousands of Rhode Islands floating around up there, no reason to worry about collisions.

Unintentional sick burn on Saturn.
