I couldn’t find any source for that, but exosphere is considered to extend to 10,000km or 190,000km, from which the latter is about halfway to the moon.
Anyways those numbers are pretty damn tiny even on a small solar system scale
One can be simultaneously on earth, and in space. In fact we all are
But I’m just arguing that while orbiting earth and being within the Earth’s atmosphere, it’s pretty much still on Earth. Just like you’re still at home even if you’re at the on the yard or even just outside the gate picking up mail from the mailbox. Looking at it from distance, it really doesn’t make difference
Extremely pedantically, sure. But under that level of pedantry, the whole metric falls apart anyway because there’s surely never or rarely been a point in recorded human history where someone hasn’t jumped/fallen/not been physically touching the ground themselves (let alone this having been measurable). What about “touching”; your feet are just repelling the ground via electromagnetism.
It’s really obvious what the metric is, and trying to pedant-proof it isn’t worth bloating it into a mouthful. We can just recognize what it obviously means, say “oh, neat”, and move on with our day.
The last time everybody was touching a solid object connected to the Earth by touching other solid objects is probably around 15,000 years ago, when humans crossed over into the Americas. Before then, it would probably occur regularly that nearly all humans are asleep and the handful that are awake happen to all be touching the ground.
I guess you could count the atmosphere as part of earth, then things over 100km are in little enough of the atmosphere that it’s not really ‘touching’ it the same way. (For example not generating significant lift)
So if orbiting earth doesn’t count as “on earth”, why does sitting in a plane just couple hundred kilometers away count?
The limit of space is widely defined as 100 km, which no commercial plane even nearly crosses.
Yeah that’s called Kármán line, but it’s just arbitrary line. ISS is still orbiting within Earth’s thermosphere
Thank you for the accents
My favorite fact is that earth’s atmosphere extends 95,000 miles / 150,000 km beyond the moon.

Yes, definitions are arbitrary but that is the definition of space.

I’m also orbiting the sun, ergo, I am a planet
It’s not like citizenship you don’t get to be a planet just because your mom is.
Look, I won’t go down without a fight like pluto did
Pussy ass Pluto.
But you are also spinning around (with) the earth, so wouldn’t that make you a moon?
Momma always told me to ‘aim for a planet, even if you miss you’ll still be a moon’
You’re part of a planet for sure :)
What does “ISS” stand for again? I forgot.
Imperial Starship. Wait, wrong comm.
But a plane is not “on earth”?

Does it really count as being “on earth” if you’re standing on a floor instead of having your feet directly touch the dirt?
