What does it Take To Deorbit A Moon In Kerbal Space Program

No... you can't deorbit moons in stock kerbal space program, the planets and moons are all on rails, but I did some number crunching to figure out what it would need.

Actually, as a black hole's mass goes up the event horizon radius increases linearly, but the volume goes up by the cube of the radius. So, as you throw more and more matter into a black hole its effective density (based on the event horizon) goes down. Black holes that are billions of solar masses would have a density roughly equivalent to that of air.

**deorbits kerbin** HAPPY END OF THE WORLD _(brought to you by danny and hyperedit)_

[@odnem]

Scott, you're my new kerbal hero! your tutorials are both fun and educational! and it made my KSP experience tripple aswesome!

[@FiksIIanzO]

You missed something: To deorbit a moon, you would need a shitload of fuel. However, this fuel isn't just present there - it has mass of it's own. In fact, in order to move a moon using fuel, you would have to move the whole system of that moon, fuel, fuel tanks and engines - all adding up to whole mass counter. That means you would need MUCH more fuel to move the moon AND itself, along with tanks and engines, and adding a single engine would mean adding more fuel, because engines, of course, have mass, too. There is another thing, however. By adding so much shit onto the moon, you would greatly increase it's mass, therefore it's gravity. It may be even enough to cancel the orbit and make the moon crash straight into the planet! Who knows? Calculations have to be done.

[@103035icle]

the weight of the fuel would be negligible compared to the satelight

[@FiksIIanzO]

It may be much less, but definitely not negligible - still thousands and thousands of tons. I'd do calculations, even, but I'm too lazy to do that.

[@Medhusalem]

Though you still won't need as much as he mentioned. He said that he would want to "deorbit" by changing the velocity of the moon to 0. You don't need to do that in order to consider a moon being deorbited.

[@FiksIIanzO]

Medhusalem Problems of definitions. Of course it depends on the body that the moon orbits around, but decreasing velocity to zero is a fool-proof way to deorbit something - say, if both objects are just physical points with zero volume.

[@arandomcommenter412]

[@blqkvo]

As an engineer and a mathematician I really enjoy the fact you bother to check the maths within the game. Keep it up!

[@LarsaXL]

So you can't deorbit a moon in the game because of game mechanics, but it would be possible in real life yes? In theory at least. If a moon was hit by a rouge planet or a huge comet/asteroid from the right angle, wouldn't that possibly deorbit the moon? Even if it shatters the moon, the force might be enough to slow down the pieces enough for them to rain down on the planet.

[@cylelangenhennig6242]

According to my physics class, if something shatters mid-flight, all the pieces will spread out, but if you averaged their distances and masses, the center of mass would still be on the same trajectory. Some pieces might get thrown off track enough to enter the atmosphere or become ejected, but the majority of them will remain in orbit. For something as large as the moon, they would probably eventually come back together due to gravity!

[@LarsaXL]

But if a moon ran into something of rougly equal mass in a head on collision, wouldn't that slow it down to near standstill? I agree that most impacts would leave what was left of the moon in orbit and it would probably pull itself back into shape eventually. Since orbit needs velocity, slowing an object down puts it in a lower orbit. If a celestial body had no velocity, then the strongest force of gravity (In a moons case, the planet it used to orbit) would just pull the object in a straight line. I agree that this is an extremely unlikely scenario, but it is a big universe and it is not impossible that something like this has happened or will happen. An impact from a large body on a moon could alter the mass of the moon significantly which would, if not totally deorbit it, then at least change its orbit distance.

[@cylelangenhennig6242]

Yes it is unlikely, but you're right. If something with equal kinetic energy (could be something less massive but moving much quicker, or equal mass and speed) hit the moon from the opposite direction, it would stop in it's tracks. It might break up a little bit, but some LARGE pieces would fall straight down to earth and would likely destroy all life, if not the entire planet. I could imagine something of that size striking the earth could break up the crust and smash it down into the mantle or something crazy like that!!

[@LarsaXL]

Let's hope that never happens. And if it does, lets hope it happens to some other planet with no life on it, but still close enough for us to observe. Though any kind of impact on the moon would slightly alter the orbit by adding more mass, or making a small change in velocity. I think. Just like everytime a meteor strikes earth, it adds to the earths mass and gravitational pull by a very small ammount.

[@tagertg2086]

SHould we just fold that under one of newtons laws : for every action there is a oppsidte and equal reaction. Considdering the materials of the object would stay togethere that is exactly how it would happend(forces canceling eachother out. But ofc , it will not. It will acctullay be more like having 2 water ballons thrown at each other. If you managed to do it perfectly.

[@sorenlily2280]

Serithi Heres the thing though. Yes you might blow up the moon with that much force at once, but other than that it wouldn't actually do anything else. All of the remaining pieces of the moon would probably continue to float around in a relatively unaltered orbit. That's just how the physics work out.

[@Dronebertios_World]

Stuart Smith that's not how the maths workout at all

[@sorenlily2280]

Patrick Sparks That is how it works but if i need to explain i will. The amount of force our mythical explosion has is incomprehensible and since moons aren't exactly designed to withstand such forces (after all they're mostly composed of rocks so its not that tough) you will break the moon apart before the explosion can apply all of its force. Picture this: You swing a baseball bat at a pane of glass. The glass breaks and the shards go flying. If you hit the glass 10X harder than that the shards don't really go much farther because most of the force of the swing is wasted due to the glass breaking. It's the same thing with our explosion. Most of the force is wasted because it doesn't hit anything once the moon starts breaking. Making the explosion more powerful won't really help because you will break the moon even more. If the moon were indestructible you might be able to make it work but otherwise, no way. If you still want to argue I will be happy to debate with you.
