Would orbital mechanics work at human scales?

Ooooh *facepalm* my bad, feeling silly now. Redid the equation and got 5.3 days.

Striking amount of error caused by a relatively small mistake.

Mass of a heavy bowling ball: about 7kg.

Radius of our orbit: Lets say half a meter.

Resulting orbital period:

2*pi*sqrt(0.5^3/(G*7)) ~ 28.5 hours.

So it isn't quite as bad as years. But still very very slow.

Eh. Sure about those units? Feels like orders of magnitude wrong! I did the math and got 28.5 x10^4 seconds, which is... eh, never mind, just about little less than thrice as yours. Science just keeps surprising me.

You did, however, use the radius where you should have used semi-major axis, which would be diameter for a circular orbit. BRAINFART. Your math is correct, sir.

edit again: LOL, just realized how many people are questioning your numbers. Science IS surprising, people!
