This talk about low orbits is just nonsense. If aliens are going to bother to come all this way to visit our star system, I'm pretty sure they'll take just a little more time to investigate the planets (and probably larger moons as well). More likely, spacefaring aliens are headed toward the galactic hub. There the star densities are much higher, providing richer "ground" for whatever it is they're looking for. -- ++---------------------------------------------------------------------------++ || Greg Paris {allegra,linus,raybed2,ccice5,brunix}!rayssd!gmp || ++---------------------------------------------------------------------------++
