If you were looking for animals but for some reason had to do it from several miles away, you'd notice a lot more elephants than mice, and for pretty much the same reason. Large planets are easier to detect than small ones.
Yes. To date scientists have discovered well over a thousand planets orbiting other stars. It is believe that a large portion of the stars in the night sky have planets.
Our nine planets orbit around the Sun. Other planets that are light-years away orbit around their suns (A sun is just a large star with planets). Hope this helped!

no, not compared to other planets around us. Think about it.
As of now, the only planet known to have its own moon is Earth. Other planets in our solar system have moons but no planets of their own. In our solar system, moons primarily orbit around planets rather than planets orbiting around other planets.

Yes. As of August 2015 scientists have discovered nearly 2,000 planets orbiting other stars.
The two other common names for celestial bodies are planets and moons. Planets are large objects that orbit around stars, while moons are natural satellites that orbit around planets.
Two in our own solar system, and nearly 1,000 in orbit around other stars.
As of now (late 2013), over 700 planets have been found to exist in orbit around other stars, and more are constantly being discovered.
Over 900 planets have been discovered orbiting other stars. These are called exoplanets.
Ceres and Eris are not planets; they are classified as dwarf planets. Eris was discovered in our solar system recently and not by the Kepler mission. Ceres is not "new" either; it was discovered the first day of the 19th. Century. I didn't check the specific "Kepler-" codes, but that looks like planets discovered by the Kepler mission to be orbiting around other stars.
