# How many Kerbins can fit in Jool?

## Recommended Posts

Title. I want one of you math peoplez to figure it out.

Welp, in theory you can fit an infinite amount of Kerbins into Jool, as long as you crash enough into them ^^

You only need the radius of both planets and use the equation of calculating sphere volumes. Not that hard, high school math.

If my maths is right just over 4,000 times

The more interesting question is whether or not adding that many Kerbins to Jool would cause it to collapse and begin nuclear fusion. I suspect the answer to be "yes". Though since Kerbin already has the density of a neutron star in our universe...things might be different. Who's to say?

And who are these "math peoplez"? All I see are those willing to learn, and those who are not.

Kerbal != Kerbin

I asked a ridiculous question and now you guys are attacking the thread for me saying math peoplez. Seriously.

Who's attacking anything? I just asked a question.

A kerbal is about the size of a 1 meter tank.

Jool is 6000 km in radius, so it's volume is about 10Ã‚Â²Ã‚Â¹ mÃ‚Â³

So it can hold about 1 zettakerbal

How much green pigment, I wonder, could you create if you then mushed-up that zettakerbal into a fine paste and extracted the green pigments.

you misinterpreted the question, he's really asking "how many volumes of the planet Kerbin would equate to the volume of the planet Jool"

now I guess hard more would be to find the circumference of Jool all on your own by flying there yourself, noting down apoapsis and periapsis, your velocity, and time from apoapsis to periapsis

then doing the same with Kerbin

After re-reading both the OP and my post, I assure you, I wasn't misinterpreting anything. The question had already been answered, so I was posing another question. I'm wondering what would happen if you took as many Kerbins as would fit in Jool, and then stick said Kerbins into Jool, if you would get a star.

Quite possibly the most awesome yet least relevant thought experiment in science to date.

I think I remember reading on these forums, that according to real physics, not even Kebol is massive enought to be a star

Kerbin is a lot denser than Jool, so even if you divided the volume of Kerbin by the volume of Jool, it still wouldn't give a conclusive answer. Just look it up on the wiki pages of Jool and Kerbin, and do the math.

You are, of course, assuming Jool is composed primarily of hydrogen & helium, which wouldn't account for it's green color.

It might as well be made of kethane.

I think someone worked out that it'd have to contain butane and fluorine or something for its colour.
