I remember when the total eclipse happened in 2017 it was supposed to pass over the city I live in. My school put us on lockdown so we couldn't see it and all we could do is look down (it was a two story school) at the awful principal and vice principal watching it and taking selfies together. It also sucked because all the teachers cleared the class schedule for the day so we had nothing to do and were not allowed to leave for even emergencies. As soon as it was over we were let out of lockdown. It was also the first eclipse I knew about before it happened and I was really excited to see it. I hate that school to this day.

[@ggtylerr]

DUDE SAMEEE ok i didnt get a lockdown (thats fucked wow) but IIRC there was both rain (in a desert!!) and i was in classes w/o any windows. same thing basically happened with the recent lunar eclipse - it was way too late for me and when i got up for 5 minutes it was too cloudy. there will be that annular eclipse next year and a total one after that, so hopefully we'll be able to actually see them!

[@Slackow]

I've heard stories of things like this happening, it's because they're worried a kid is gonna be blinded by the sun when trying to see the eclipse. Which is a genuine concern. I can't really think of a good solution to this that doesn't run a sizable risk of a kid not listening and blinding themselves. It still sucks though.

[@hsviabgsjsbsjsbsn]

Cary's videos are always cool to watch :)

[@leave-a-comment-at-the-door]

Nerd here, 9:15 is a bit inaccurate. What you want is the Hill sphere, which is the area within which a celestial body is the dominant gravitational force. To calculate, when a moon orbits a planet which orbits a star, assuming orbits are circular, the maximum radius of the Moon around the Planet is the radius of the Planet's orbit around the Star times the cube root of ( the mass of the Planet divided by three times the mass of the Star ) A bit more coherently, assume circular orbits rM = outer limit for the orbit of the small object; rP = radius of the orbit of the middle object; mP = middle object mass; mS = big object mass rM < rP * cube root (mP/3mS)

[@patrickskelly8517]

So since the Sun is 300,000x more massive than Earth, rM is 100x smaller than rP. And for the Moon around Earth, rM is about 6x smaller than rP. His guess of 5 to 10x worked out pretty well for that one.

[@vari1535]

Oh my god, thank you SO MUCH for the visual demonstration of why eclipses don't happen twice every month. I was told in school that it only happens when the sun, earth, and moon line up and that the moon's orbit was on an incline and that that's the reason they were rare, but I could never actually visualize it in my head and fully understand it! Sometimes KZbin _is_ better than school.

[@IGNACIOSOLAR1]

Got the full Santiago experience with your passport being stolen, loved the video and the visualization, greetings from Chile

[@EnergySurge]

8:23 "... make the inclination 90 degrees which basically tilts it up on its side like the planet Uranus" No, that won't be like Uranus. You're comparing orbital inclination to axial tilt. Yes, Uranus's axial tilt is 97.77° with respect to its orbit. But this makes it appear to rotate sideways, not orbit sideways. Uranus's inclination is 0.773° to the ecliptic, 6.48° to the Sun's equator and 0.99° to the invariable plane. All the planets have fairly similar inclinations for all three of these reference planes. Earth is 0, 7.155° and 1.57°. This is why all the planets orbit roughly in the same plane. When "all the planets" included Pluto, Pluto had a noticeably inclined orbit compared to the rest of the planets because Pluto's orbital inclinations are 17.14°, 11.88° and 15.55°.

You're right about the moon's moon having a size limit. It's got a particular name. All I remember that if you calculate it for the ISS around Earth you get 2m EDIT So I went and looked it up, it's the Hill Sphere. R = [semi-major axis] * cube root( [smaller mass] / 3 * [larger mass] ) For the Moon this is about 60,000 km. Though practically this would be more like 30-40,000 km

[@CHKNSkratch]

so if an astronaut got into an orbit 2m around the ISS he would have no hope? I have a plan

I remember the 2017 eclipse. My city was directly in the path of totality, and my school let us have some time off to watch it. I don’t remember the exact numbers, but I remember leading up to the eclipse hearing estimates that somewhere around 3 to 4 times my cities population was going to come as tourists to see the eclipse. Still have some eclipse glasses nearly five years later!

The extent of an object's gravitational hold (where it can have an orbital) when under the influence of a bigger object is known as the object's hill sphere. Our moons hills sphere is about 60,000 km, so that's the max distance an object can orbit the moon

[@spcxplrr]

the question of where a moon can be placed depends on a bodies hill sphere, which depends on the masses of the main body, the parent body, and the distance between them. for example, neptunes' hill sphere is bigger than uranus's, because neptune is further from the sun, even if they are similar masses.

[@leave-a-comment-at-the-door]

Oh snap, you beat me by four hours. I just commented basically the same thing... For convenience, here's the timestamp 9:15 and calculation To calculate, when a moon orbits a planet which orbits a star, assuming orbits are circular, the maximum radius of the Moon around the Planet is the radius of the Planet's orbit around the Star, times the cube root of ( the mass of the Planet divided by three times the mass of the Star ) A bit more coherently, assume circular orbits rM = outer limit for the orbit of the small object; rP = radius of the orbit of the middle object; mP = middle object mass; mS = big object mass rM < rP * cube root (mP/3mS)

[@zsomborfekete9973]

What's really fascinating to me is that even on this astronomically small scale the speed of light has a distorting effect. The light from the Sun takes more than 8 minutes to get here, while the Moon is only roughly 1 light seconds away - we see their past positions, but on a different scale. So for us to experience a total solar eclipse, the Sun and the Moon shouldn't be in a perfect overlap, but it's the Sun's historical position 8 minutes ago which must be aligned with the Moon and the Earth.

[@olfmombach260]

The moon is about half a lightsecond away. It just takes us about a second to see a laser _come back_ to us.

[@zsomborfekete9973]

@@olfmombach260 The Moon is 384,400 kms away on average, so it's about 1.3 seconds one-way. But my point was that it's still more than 8 minutes earlier where we see the Sun on the sky, so if we see them overlap it means the Sun's past position overlaps with the Moon's current position. Meaning in reality they are never perfectly aligned during a total solar eclipse.
