QUESTION:
How many planets can you see from Mars?

ANSWER from Smartfilter on January 12th 1997:
Since Mars has a thinner atmosphere and is situated farther from the sun
than the Earth, you can probably see more stars at night.
And since Mars' distance to the other
planets in our solar system is closer to the outer planets, and
farther from the inner planets we could still see all eight planets
with a telescope or CCD camera including our own Earth.
