Build-a-Moonmoon

We all know about moonmoons. I think the article puts it best: "moons can have moons, and they're called moonmoons."

This challenge is simple. Capture an asteroid, and give a moon a moon. It doesn't matter which moon in KSP is moon'd. Entrants will be sorted by mass of the completed moon. You're welcome to stitch asteroids together, too. Bonus points for far away moons.

Winners get the badge below! If you want to make a better one, please do; I'm not very good at GIMP.

ENTRANTS:

KingDominoIII - 884 tonnes

Sky Vagrant - 415 tonnes

Johnster_Space_Program - 143 tonnes

SecondChance - 114 tonnes

It helps to read the up completely

Add me to the entrants, im going to try this! @KingDominoIII

This one looks good:

Looks like a great challenge! If I could only catch an asteroid I would be tempted to enter.

I do, however, have one suggestion: Please fix the capitalization and dashes in the title.

Setting up encounter with e-class asteroid:

Doing maneuver and some fine tuning:

Here's my own submission. I'm sure it can be surpassed, especially by chaining together asteroids.

I was so happy to read

A moon of a moon has no formal name, perhaps because we have never spotted one, but both submoon and moonmoon have been suggested.

So I don't have to even consider the possibility of getting used to the word "moonmoon."

How about "metamoon" ?

Gonna try and get this c-class intead:

Its coming in at a pretty good angle

I got this asteroid fine!

I'm gonna go and try to go for the far away moon of minmus for bonus points.

time to put it in minmus orbit, then my submission so far will be done:

[Johnster_Space_Program]

Here's my submission @KingDominoIII:

Asteroid Type: C-class

Mass: 142.9 tons

Orbit: Minmus - 54,042m  x 54,239 m

I know I can do better later but for now, this will do.

Was just looking for the Jool 5 thread (searchbar is probably easier lol), and stumbled across this.

A couple of things. Doesn't Lathye make this quite easy, due to aerocapture? And how big is Gilly? Becuase is it really a moonmoon if the object you put in orbit is bigger than the original moon? In fact it likely shows a fatal flaw in the physics engine.

Actually you may find making something bigger than Gilly to be a bigger challenge than you'd think.

Well I'm more looking at it as a joke, becuase then the orbits should be reversed, but they won't be. Don't know if someone will go to the effort for such a small payoff, but we shall see.

Well yes, but no.

Laythe is really freakin' far from asteroids. You can't really capture a Dresteroid without canceling out the Oberth effect, and getting a kilotonne payload craft or so to Jool is pretty much impossible. Also, asteroids have incredibly low heat tolerance for an object you can't spin around to dissipate heat.

I know you're joking, but I did the math (really research) anyway.

Gilly weighs 1.2E14 tonnes. The biggest asteroid I've seen is one kilotonne. Gilly is .12 petatonnes. That's a difference in magnitude of 14. That's huge! The Earth weighs only about 81 times more than the moon. Gilly is huge, it's just that gravity is an extraordinarily weak force.

So using Duna to aerocapture then putting the asteroid next to Ike is better?

Also why am I not surprised  KSP players works out the maths on EVERYTHING. Do you not have days off?

But anyway, yikes. That's 12 with 14 zeroes if I'm not mistaken (1,200,000,000,000,000 for those that want to see the actual number). By the time you finished, Squad would have released more planets to explore

Probably easier, although it's easiest to just go to the Mun. Duna aerocapture is most likely the best option, yeah, considering the size of Ike and how likely you are to get an encounter with an elliptical orbit. Of course, if you find a highly eccentric asteroid you could always work around that.

1.2E14 is 12 with 13 zeroes, 120,000,000,000,000.

I actually did this not long ago! I have a pic but will have to check my save later for mass and orbit specifics its class C though (I'll update this post once I'm home), met it out in solar orbit which was very fun! I reckon I have enough fuel left over to hop it back over to Minmus too! Yes the craft is overbuilt but I had contract to put it in orbit of kerbin, Mun and Minmus so that's why

Also someone with the required artistic talent should make a badge for this!

Very cool! I'll put you on when you submit the details. 

If anyone's interested I'd definitely adopt one!

[Ratwerke_Actual]

Maybe I can launch something large enough to move this....

Worth a try.

[Whirligig Girl]

I don't suppose modding in a moonmoonmoon counts? This is Diddmun, orbiting Didd, which orbits Manonam, moon of Valyr, which is a planet in the Whirligig World mod.

Good luck, remember to save to avoid the Kraken.

No, but it would certainly count if you made a moonmoonmoonmoon!
