Isn't Pluto part of the solar system now?

A. 1

Pluto was first discovered in the 1930s.
At this time, astronomical equipment was not as developed as it is now, so it was thought to have the size of the earth.
Since then, surveys have shown that it is smaller than the moon and has been difficult to call it a planet in terms of mass and gravity.
And the orbit around the other solar system planets are also orbiting themselves at some distance, and Pluto has also invaded the interior of Neptune's interior.
Considering these various aspects, the International Astronomical Union ruled out Pluto from the planets in the solar system in 2006.
Instead, it gave it status as a dwarf planet and designated it as asteroid number 134340.
