the moon or digable planets?

That's no moon!

1. It must be an object which independently orbits the Sun
2. It must have enough mass so that gravity pulls it into a roughly speroidal shape
3. It must be large enough to "dominate" its orbit (ie. its mass must be much larger than anything else which crosses its orbit

1. Neither
2. Moon is spherical, moon wins
3. Neither

Moon satisfies one of the three conditions, a websitewith a bunch of inhabitants connecting via the internet satisfy none.

Winner: Moon
