i was just thinking for some random reason, that it would be very clever to hide something by having it orbit the moon while always staying in the
earths shadow, we would never see it.
The premise was actually used in the TV show V. For that matter, any planets in the solar system would work as well, even better. Yep, an alien fleet
could very easily sneak right up on us.
Mind you, it would only be easy to hide something extra terrestrial
I doubt we could hide Something that big (as it would have to be self sustainable to be constantly hidden) into space without hearing about it.
Therefore i highly doubt there could be anything terrestrial up there .
(Unless ofcorse we have crafts that use a much more advanced propulsion that is queit and non detectable)
