"Have
any of you seen a satellite?" This is a trick question, because
the answer is that the Moon is a natural satellite in orbit about
the Earth. Actually you can see man-made satellites too. On a clear
night, go outside (with plenty of bug spray) and lie on your back
with your head facing North. After your eyes have adjusted to the
dark, you will begin to see what looks like moving stars -- moving
from north to south or vice versa. It will take the "star"
just a few minutes to travel from horizon to horizon.
