Astronomers must learn physics, chemistry, mathematics and computer science...and how to use a telescope, astronomers must rely on their observation skills, for instance physics has helped astronomers to understand what makes spiral galaxies have spiral shapes, another is Spectroscopy which is the use of light from a distant object to work out the object is made of, When something is moving away from you, it stretches that waveform, while if it moves towards you it compresses the signal wavelength it emits. Spectroscopy also tells you a star's temperature, mass and surface gravity.

Mainly astronomers. But cosmologists and astrophysicists will also be interested in outer space.
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.
No, astronomers have not physically gone out of the solar system. They study space and celestial bodies using telescopes and spacecraft like Voyager 1, which has reached interstellar space but is still within the boundaries of our solar system. Astronomers rely on these tools to explore the universe beyond our solar system.

Many astronomers, historians, regular people, and scientisis know about the planets in our Solar system.

Astronomers study Jovian planets like Jupiter and Saturn to better understand planetary formation and evolution in our solar system and beyond. These planets can provide insights into the conditions present during the early days of the solar system. Additionally, studying these gas giants can also help scientists understand the processes that drive the behavior of exoplanets.
