A solar eclipse has been witnessed on Easter Island 12/07/2010
and as part of the editorial:
The sun is 400 times wider than the moon, but it is also 400 times further away. Because of the symmetry, the lunar umbra that falls on the face of the Earth is exactly wide enough to cover the face of the sun.

Now the probablity nutters can have a go at this because I reckon the probability of this sort of coincidence [acka 400,400] is staggering-ly remote. Give the variables and scale.
care to discuss?
