Formation.
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust.
The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova..
But do we know how many planets are out there? Astronomers have discovered 5,502 planets around other stars (known as exoplanets) in the Milky Way.
Add in the eight in our solar system (not nine, sorry Pluto), and that gives us a total of 5,510 known planets, all located in our own galaxy..
By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth.
In astronomy, the Universe is our laboratory.

Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto.
The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Mercury is closest to the Sun.
Neptune is the farthest..
To answer your question succinctly, the Solar System also goes by the names: The Copernican System, The Heliocentric System, and The Planetary System, in addition to the ones you have mentioned.
There aren't too many other names, actually, so just stick to Solar System since it's the most widely accepted..
