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/

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.

not to split hairs that was gaining/catching a moon, not loosing a moon. Though catching Triton would probably have created chaos for Neptunes moons too. (To your credit, the Mars example didn't really seem to apply also)

Tearing its children apart IS appropriate for Saturn, in this case!

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

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

5:18 “The team noticed that the moons orbit on opposite sides but the same distance from Mars.” Since when? According to JPL, Phobos has an orbital diameter of 9400 km and an orbital period of 7.66 hours, and Deimos has an orbital diameter of 23500 km and an orbital period of 30.3 hours.

Does anyone think that a sucked and Moon could be the reason for the big red spot on Jupiter? I know that the center of Jupiter is probably comparatively small, but could it be that when the moons hit they create some kind of a feature which then causes the storms to shape the way they do as we see them at the surface?

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.

Interesting.

Wait. Wait! What's the deal with Saturn's tilt and what's the other theory? You cannot just casually throw these things in the air and not elaborate further. We need to know! Come back with a video about this imediatelly! I need to know about the tilt!

Jupiter eating it's moons sounds familiar lol

How did the astronomers suggest Phobos and Deimos get smashed apart a billion years ago? There weren't astronomers back then.

Well I mean Earth practically stole a whole ass planet and made it into a moon.

I found it! They where left in the door lol

Perhaps most moons are composed of mostly regolith?

Well, Jupiter has a moon named Metis so... she's next.

So 99% of our Solar System's mass is in the Sun. And of the remaining 1%, 99% of that is in Jupiter. And of the stuff orbiting Jupiter, 99% of that is in four of its moons.

So how many moons did Saturn destroy because I know one moon was big enough to create that massive ring!???!!

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.

I have now watched two SciShow Space videos, and I will never watch another one again. I am intelligent, not in your target audience.

Andrei, You've lost another submarine?

5:18 Mars' moons DO NOT orbit opposite sides of Mars at the same distance, that is absurd. Phobos orbits more than twice as close as Deimos and hence at a different rate, so they could never remain on opposite sides of Mars for more than a few minutes. Who wrote this?! Why did Savannah read this silly thing?
