Why we can see some planets but not others

SUBJECTS:  Science

YEARS:  5–6

Why is it that we can't always see the planets?

In this planetarium demonstration, the air has been sucked out of the sky to give us a black sky so we can actually see the planets that are above us.

How does our proximity to the sun affect how visible a planet is to us?
