It would be nice to get a perspective of an eclipse from the vantage point of the moon.... We likely will in the near future.

It's worth mentioning that the nodes of the Moon's orbit shifts every year thus making the time of eclipse seasons shift accordingly.

The last part of the explanation is that yes, you'd still get about 1 to 2 eclipses a year, but 75% of the Earth's surface is water, so it's even rarer for it to occur over land, let along inhabited land. Eclipse cruises are also totally a thing.

I need like an entire documentary just filled with diagrams of the earth, sun, and moon to fully wrap my brain around the way they all move around. 😵‍💫

This question pursued me as a kid. Since I learned about the celestial bodies and eclipses I made the same question (at around 7 to 8 years old), but the teacher for some reason explained in way I didn't understand, probably something around "because of seasons". WTF I kept in my mind but only after two years later asking another teacher about it, while trying to draw the moon and earth in the air with my hands, she just said "because they aren't aligned, they are spinning on different planes". It just clicked for me.

The animation in this video was top notch! Great work!

That is so elegantly described. I love it. It borders on art.

Simple and straightforward. I knew that was the reason, but here the visuals and clarity make a great explanation. Way better than my astronomy class at High school.

I've wondered this for ages! Thank you

My man Ferguson knew that we'd land on the moon someday and decided to account for it in his explanation. Smart man, he was.

In short, space isn't a flat plane. Therefore, eclipses can only happen when the moon lines up with the sun and the earth such to create a straight line.

Amazing and intuitive animation at the end. Great work!

the nodes are the points of intersection between the moon's orbit and the earth's orbit (i.e. where the moon's path crosses the earth's path. like a gyroscope. relative to the moon or the earth, the nodes dont move. relative to a spaceman observing the entire solar system, the nodes appear to move with earth's orbit.

@thenefariousnerd7910

The moon does not cross the nodes of its orbit at the same time every year. The moon undergoes “nodal precession” (like the precession of a gyroscope) which means that the positions of the nodes gradually orbit Earth in such a way that they complete a full rotation every 18.6 years. The upshot is that the two dates each year that a solar eclipse occurs somewhere on Earth drifts back in the calendar each year by about 19 days (+/- 17 days).
