No. There is much more out there that is still to be discovered. The solar sytem consist of all sort of things, big and small, so there is more to be found.

Astronomers believe that the solar system formed from a giant rotating cloud of gas and dust called the solar nebula. As the cloud collapsed under its own gravity, it began to spin faster and eventually formed a flat, rotating disk. The Sun formed at the center, while the planets and other objects in the solar system accreted from the material in the disk.
The scientists who studies planets or heavenly bodies are astronomers. They study by looking from the telescope at night and recording it. Afterwards, they give the information they've found.
Depends who you ask. There's an astronomers' joke that since Jupiter is more massive than all the other planets put together, an alien scout would probably report on our solar system as "A single star, one planet, and some debris." If one allows Mercury-sized objects into the Planet Club, then the analysis is that the asteroids and the Kuiper Belt Objects and the Oort Cloud planetisimals are the debris.
If the objects are in orbit around the sun then they are in the Solar System.

Protoplanets are very small planets, about the size of a moon. Astronomers believe these celestial objects are formed during the creation of a solar system.

People thought the earth was in the center of the solar system
Many astronomers, historians, regular people, and scientisis know about the planets in our Solar system.

Mainly astronomers. But cosmologists and astrophysicists will also be interested in outer space.
