So is Kerbin's day 6 hours then?

[Noteak]

I have landed on the Mun and just landed for the first time on Minmus when I noticed when calculating till throttle up it was 6 hours to a day. Just curious if this is supposed to happen or if I am misinterpretting it.

The entire solar system is 'too' small. If it was full size, or 1:1 scale, the sort of physics would be a little to complicated for the purpose; essentially, it is easier at this scale, and changing it would basically mean starting again.

[Noteak]

I'm not mad I just thought is was funny it took me enough experience to get to minmus to finaly find out the truth lol.

6 hours a day, 425 [6 hour] days a year.

[Noteak]

Interesting...

The complication of the physics has nothing to do with why it was made small.
It was made small to help alleviate boredom. Faster orbits, quicker planetary transfers, etc.

I'm about 90% sure that there's a mod that turns the Kerbal solar system into our own system, including scale. I can't remember the name of it though.

RSS, Real Solar System[forum.kerbalspaceprogram.com]

In the last version "Kerbin time" was added and yes this has 6 hour days and 400 something day long years. I think that if you click your timer you can toggle between Earth time and Kerbin time.

This^^

I have a few pieces of RSS, but I believe KSP stock now allows for Earth Time to be set via the Settings menu before opening up saves.

Yeah, to be honest it took me a bit to notice this.
The first time i noticed it was when i was at max time speed and was trying to estimate how long it would be.

As for the size of the system, I love realism in games like this. But when the realism would only make you sit there another hour at max x time speed and add nothing really of value then i see no reason why it should be there. So long as the Fuel/speeds/ and everything else is scaled around that ratio things should still be fairly realistic without the extra dead time of nothing happening. Pretty sure the time scale for the kerbel system is a time scale to pass the days and years by more accurately compared to the relative size of the system.

@axebyte when you swtich to "Earth Time" the changes are mainly for time dilation for a surface day, so on the surface of Kerbin you see a 24H day, however it seems like the T+ time counter seems to follow the original time dilation, so 1 Kerbin day still yields 6 "days" of time passed; In other words the scale of motion around the universe seems to stay constant, but the axial rotations for each celestial body. But I might need to do some more testing to ensure this is the case.

Yes Noteak, Kerbin's day is about 6h 50s.

Moon - Earth / Mun - Kerbin

As the orbit period of our Moon is equal to its rotation period (that's why we always see only one side of our Moon) also Mun's sidereal period and its rotation period around Kerbin is eqeual.

A solar day of our Moon differs from the sidereal period because its rotation around Earth and together with the Earth around the Sun:

Earth's siderial day takes 23h 56m, a solar day 24h. Moon's siderial day takes 27.3d and its solar day 29.5d.

Kerbin's sidereal day is 6h and it's solar day 6h 50s. Mun's sidereal day is 1d 14h. There are no informations about it's solar day but it is longer than this 1d 14h.

Yes there is: it's equal to its synodic orbital period (with respect to Sun-Kerbin) which is 141115.4 s. I trust you can do the math to turn that into days/hours/minutes/seconds yourself.

[Belami]

Yes Rene - thank you. Mun's solar day is then 1d 15h 11m

[I3laze]

Sorry to rez but I'm a little thick and confused as to how many hours are in 1 day for the mun? Is it 38hrs 36 mins? If so does that mean it takes 38hrs 36 mins to do a full rotation around its axis? 6days and 2hrs and 36min kerbin time? I'm confused as to what it means that the mun orbit period is 1 day and 14hrs, when Kerbin is 6hrs for a day.

I'm now confused with my own question lol
