If the Moon were replaced with some of our planets
Yeti Dynamics shows us what if the moon were replaced with some of our planets:
On Jupiter, you might be able to make out the 4 big moons, They all have orbits larger than our moons orbit. but I stuck them on the far side of jupiter so that they could be seen so it looks as if they are closer (to Jupiter) than they really are.
Another video from them showing what if the moon were at the same distance as the International Space Station is also fascinating.
