who explored the solar system
The solar system is natural.
There has never been a man made object to leave the Solar System. There are however, two objects which may escape the influence of Sol and enter the interstellar medium. These objects are the Voyager 1 and Voyager 2 spacecraft. It is currently unknown which will leave the system first, as although Voyager 1 was launched first, peculiarities of the nature of the Solar System may mean that Voyager 2 breaks the heliosphere first.
There are 9 planets in our solar system, which is the Milkey way Galexy.

Nothing man-made has left our solar system yet. The furthest thing is Voyager 1, which is now about 116AU away from Earth, around 10.8 billion miles - at the edge of our solar system.
CERES is the first and the biggest asteroids in the solar system
Not in my solar system.
That depends on what definition of first you mean. A solar system is in a galaxy and a galaxy is in space. So the solar system is smallest and space is largest.
