Why don’t they ever show you this star with planets?
Simple, no one has ever seen a planet in any other solar system. When we look at a star all we ever see is a Dot.

Stars are simply too far away to actually see the planets but there are many clever ways to find out what is going on. Starlight has lots of information in it. As a star moves towards or away from us that changes the light much like the sound of a train changes as it does the same.

Starlight even has chemical information in it as well because of the ways atoms emit light when hot.
