There are a number of sources for data about the solar system. I recommend the web site below "The Nine Planets" as an excellent basic reference.
Solar System
i think it's Kepler
It's not; normally scientists use satellite telescopes and send them around the solar system to take pictures and record data of the planet.
Kepler used Tycho Brahe's data to establish the heliocentric theory of the solar system.
Voyager 2 is currently in interstellar space, having crossed the boundary of our solar system in 2018. It continues to transmit valuable data back to Earth, contributing to our understanding of the outer regions of our galaxy.
"Our solar system." The "part of our galaxy" that's in our solar system is the solar system.
Our Solar System is called the Solar System, Why?, what do you Aliens call it.
No. There is one star in our solar system, and no other solar systems within it.
The solar system
My solar system (and yours if you are from Earth) is just called "The Solar System".
When the Moon was formed, the Solar System WAS already a solar system.
There are no exoplanets in our solar system. By definition, an exoplanet is a planet that is not in our solar system.
