Collectively they are called Astronomers and Astrophysicists. Either professionals or amateurs.
There are many types of astronomers, defined by how they study the stars. The most well-known are those that use optical telescopes followed closely by those that use Radio-telescope to pick up wavelengths other than visible light. there are many others and many other ways to collect data on the galaxies and stars.
Astrophysicists are astronomers and may also collect direct data, yet they are more interested in the working behind the data. They deal in physics and theories of the galaxies.

There are zero galaxies in our Solar System. Even the smallest galaxies are much, much larger than the solar system.
No. Galaxies are well beyond our solar system. Our solar system is just one tiny part of the Milky Way Galaxy.
That is backwards, galaxies are much larger than solar systems.
Galaxies are larger than solar systems. Galaxies contain solar systems.
The Solar System is inside the Galaxy the Milky Way
No, it's the other way round. There are millions of solar systems in galaxies.
All of them. The Solar System is part of the Milky Way Galaxy, one of several billion galaxies in the Universe.
We need to learn about solar system, galaxies and universe because it will help us in the future....
