Scaled speed of planets and moons doesn't add up?
Science Fiction

So I am working on a simulation of the solar system and ran into a roadblock...


In reality, the speed of the moon compared to the earth is much slower then that of the earth compared to the sun. However, the moon completes its orbit much quicker because it has to travel much less distance. The moon orbits the earth about 13 times in 1 year.


In my simulation however, the moon gets maybe 2 orbits in a year...


I've checked the speed with wikipedia and they are correct.


The only difference is that I scale everything, making me suspect that that's the cause.


All distances are devided by 100 000
