In 2006, the International Astronomical Union (IAU) redefined the large planets in the solar system, resulting in Pluto being excluded from the nine planets in the solar system
Recently, astronomers have pointed out that Pluto is the ninth planet in the solar system because it operates in a special area of the solar system, the Kuiper Belt, and has proved to be the second most complex, most interesting and more dynamic object in the solar system than Mars
There are other celestial bodies around Pluto's orbit, and even its moons are half its own size.
