How the Moon orbits Earth

- Using real data for the month of April 2020 I'm showing the exact rotations, tilts, inclination, orbital velocity, sunlight angles & views of our Earth-Moon system. Earth-Moon distance is not to scale, but Earth and Moon sizes are (in the middle row).
FAQs/info
1. The green caps on the Moon are to indicate the position of the poles
2. The green circle around Earth (bottom middle, lol, middle Earth) is just a reference
3. The Moon is tilted 1.5° to its orbit around the Sun, so it has virtually no seasons
4. When the Moon is close to Earth it's pulled more strongly by Earth's gravity, so it goes faster, but when the Moon is far, it's pulled less and goes slower
5. Remember the SUPERMOON the other day? On April 7-8 have a look how there was a full Moon during a time when the Moon was closest to Earth... and you'll know why it looked bigger. A nice coincidence
6. Because of the 5.1° inclination and 1.5° axial tilt of the Moon, we actually see ~6.6° beneath and above the Moon's poles during it's orbit, which is why it looks like it wobbles up and down, from our point of view
