Thank you to everyone who noticed the mistake in this video! Mars's moons Phobos and Deimos do not orbit on opposite sides of Mars at the same distance! The researchers noted that the moons orbit on opposites sides of "the location where the orbital period about Mars equals the rotation period of Mars," or the synchronous radius. You can read more about this in the paper here: www.lpi.usra.edu/planetary_news/2021/03/08/exploring-the-origin-of-mars-moons/

Earth also lost another moon, according to latest NASA simulation After Theia collision, materials ejected into Earth orbit coalesced into 2 objects: larger clump and the smaller one. The larger clump interacted with the smaller one, which exchanged their energy: the bigger one lost orbital energy and falling back into Earth, the smaller one received energy transfered from the larger one and pushing it into higher orbit which secured its position. The smaller clump became Luna

There were another moon After the theia collision the second moon was 3 times smaller than The Moon and it was much further from earth. The Smaller Second Moon Collided with The Moon in the Lunar South pole and Splattered it self in the surface of The Moon as a extra layer of crust the collision was cause by The Moon drifting away from the earth

I'm surprised you didn't mention Neptune and Triton, a prime example of lost moons. Triton makes up 99% of the mass of all Neptune's moons, suggesting that after it was captured, Neptune's other moons all collided with Neptune or Triton, or were ejected from the system altogether.

Agreed. The strange similarity is that they both have circular-ish orbits near the equator which would be strange if they are captured asteroids but they are at way different altitudes and orbit past each other all the time. I bet the writers of the paper would be astonished to hear the line about opposite sides and same distance from Mars.

This is actually part of the argument. The initial paper argued that the moons WERE at the same distance with the breakup leading to an increasing separation due to atmospheric drag on the innermost moon. The rebuttal claims to show that this doesn't add up. As you can guess the original claim is far from watertight.

Does anyone think that a sucked and Moon could be the reason for the big red spot on Jupiter?

Ironically a moon is generally considered to need to have a clear orbit (Not to have CLEARED its orbit, which is different.) The ring fragments don't 'count' since they're part of a crowded system, though there are 'shepherd moons' which keep some of the rings in place or distinct. A similar issue plagues Earth, which has had a few temporary 'natural satellites' in its orbit in human history.
