Arguably, the entire heliosphere is part of the Sun's atmosphere, and it reaches well beyond Pluto. If I were in a relativistic spaceship, I think I'd want to apply the brakes well before slamming into the heliosphere.
What do you call the heliosphere of a star that isn't the Sun? The stellosphere?
- denton-scratch 3y agoReplying to self (sorry). "Stellosphere" is wrong, because "stella" is Latin, and "sphere" is from Greek. It should be "asterosphere", but that's a word I've never seen nor heard.
- eru 3y agoWe have been mixing up Latin and Greek for quite a few terms already, so I don't think that should keep you from using a term.
