KSP space size How Much?

Anyone know? Ä°t is endless?

The SOI for Kerbol is infinity..

What is SOI ?

Sphere of influence.

eventually your your floats run out of precision and the kracken starts eating things.

Indeed. Which makes it hard to set an absolute upper limit. One of the first bugs to show up is the Space Centre looking like it's built on corrugated ground when you return to it.

I believe the altimeter can go into the Exametre range

I don't know what manner of precision KSP's software/variables uses, but I'm sure it's documented somewhere. Celestia's math package had very good precision out to somewhere around 16k light years, its precision matching that of the valid parallaxes of star distances measured by Hipparcos. I'm sure the same could be done (or has been done?) with KSP? If not, it should.

Bit off-topic, but I wonder how Space Engine handles intergalactic distances. You can travel an almost arbitrary distance from earth in Space Engine and see no floating point errors (That I noticed). The universe in Space Engine does have an edge, though, beyond which no galaxies are generated (But you can still fly the camera out there).

I'm tempted to try and make an all-stock extrasolar mission.... just to see how far I can get in .90 (I'd likely find a K-Drive to power the ship, since I don't feel like launching a full heavy lift rocket into LKO for the departure burn).

I think that's because the physics in that game is different. Either that or it's not using Unity.

If you go out too far the 'Big Beige Men' abduct you...

idk about se but orbiter uses moving frames of reference to keep the precision within tolerances. you can also do some kind of large fixed point format such as 95:32, which would give you 29 orders of magnitude on the integer side to work with. i think ksp only needs 13 orders of magnitude. newer instruction sets could make short work out of that math. but i think floating point units might be faster than the alu.

About 3 gigabytes.

...wait.
