They've never bothered to set a definition for that. Maybe they're still freaked out over getting death threats from taking away Pluto's status.5 kilometers across? how big does something have to be to be considered a moon? If we want to have a most moons fight between Jupiter and Saturn we can get really pedantic and go down to moonlets and debris and say that each planet has millions of moons.
Also if neither of those happened for some reason you'd die anyway because hydrogen sulfide is poisonous to humans.They actually will smell like shit since they have lots of hydrogen sulfide (aka rotten eggs) in their atmosphere. Fortunately, if you try and smell it you'll freeze to death in seconds if you don't asphyxiate first.
Cool, I'm going with Obelix."This time, the moons must be named after giants from Norse, Gallic or Inuit mythology."
There was a hypothesis where Pluto was supposed to be a moon of Neptune lost somewhere along the way. But it's outdated I think, now everyone believes Pluto is just another overgrown Kuiper Belt iceball.I don't remember where but I can't find anything about it, weird. Anyway it's always good to get misconceptions cleared up.
You're on to something here. Sheppard is a specialist in discovering these tiny moons, he's got literally dozens to his name and they're all estimated to be a few kilometers across. Earth-based telescopes probably can't pick up anything smaller out there. However, there's this thing called S/2009 S1 that's 300 meters across and was discovered by Cassini. I don't know if it officially counts as a moon or not, Wikipedia list is as one at least, and so does the fact sheet at NASA. Either way it's a propeller moonlet, a type of rock floating inside Saturn's rings that can only be found because they distort their shape locally. Astronomers are estimating that there can be thousands of such propeller moonlets, so if they ever send a probe to count them all, either there will be a redefiniton of the term "moon" happening, or everyone is going to bitch and moan about the fact that Saturn now has 10.000 moons or so.5 kilometers across? how big does something have to be to be considered a moon? If we want to have a most moons fight between Jupiter and Saturn we can get really pedantic and go down to moonlets and debris and say that each planet has millions of moons.
You might be thinking of the idea that Pluto might be Neptune's old moon as an explanation for why it's so weird.Isn't Pluto considered Neptune's moon? Or it was going to become Uranus' moon in a couple hundred years. I forget the details but hopefully one day we just nuke it into dust so we can stop worrying about classifying it.
