Can someone check my answer:
Does the Moon travel it's own diameter in about 3.34 seconds?
(Relative to the Earth)
So if it passed directly in front of a star, does it only take 3.34 seconds for that star to reappear on the other side?
Working to follow ...
Distance to the Moon is about 390 Megameters, time to orbit is 27.32 days, so speed in m/s is:
D*2*pi/T/86400 ~ 1040 m/s
Diameter is about 3500 m, so time of occlusion is:
3500/1040 ~ 3.36
More accurately, diameter ~ 3475m, hence
3475/1040 ~ 3.34.
Seems low to me.
