Interesting mix of kilometers and inches…
As a Canadian, this just seems normal to me.
Is our moon really that big? I thought Charon-Pluto is kinda a special cases that they look like twin planets instead
I think part of it is that Mt Everest is a lot smaller than you’d think when you’re looking at this scale. The moon is only 2% of the Earths volume so when you spread it over the Earths surface it’s really like a thin thin film to cover the whole surface. But the truth is that all of human experience is an even thinner film smeared across the surface.
One of my all-time favourite facts is that solar eclipses are actually a very rare thing to happen in space. There is no reason why but our moon just happens to be the right size/distance to have this happen.
I’ve never seen one in person, but the next one is on the 8th of April crossing Mexico and the US. If you have the chance and are able, go check it out, if only to gloat on an internet stranger longing for his first total eclipse.
I’m gonna be dead center for it here in Ohio, so excited. Got my welding helmet ready to watch it and the day off.
Fuck yes, enjoy bud. I’ve read people not using high enough rated welding goggles and getting eye damage though. I’d stay on the safe side and get appropriate solar eclipse glasses. You’ll be looking directly at the sun for several minutes after all.
I have shade 14 capable welding helmets, I’m good. I did have to look that up to be sure though. You are right apparently to be worried.
