extra solar planets are not bright compared to the stars they orbit
9. Actually, there are 8 planets in our solar system. Pluto is no longer considered a planet. However, we have now found approx. 400 extra-solar planets, or planets in other star systems.
Potentially yes. We do not have the technology to get people out very far (maybe as far as Mars at present, but even that's debateable), but in theory we would be able to visit extra-solar planets as technology improves in the future.
Yes, there are planets outside our solar system known as exoplanets. These planets orbit stars other than the Sun. Thousands of exoplanets have been discovered so far using various techniques like the transit method and radial velocity method.
Most likely there are. But just detecting the presence of the 'extra-solar' planets is so delicate and difficult, we don't have the ability yet to detect the presence of their satellites.
