2006
In the year 2006.Pluto was demoted because it did not have an orbit of its own, but shared its orbit with other Kuiper belt objects (KBOs).(The link below should help answer your question better)
Pluto was ranked down to a dwarf planet in 2006
In 2006, pluto's classification was changed to "dwarf planet". This removed it as one of the nine planets in our solar system. It was done so by the IAU (international astronomical union). The main reason for this is due to the orbital path of Pluto as it crosses Neptune's and thus does not fit the IAU's definition of a "planet".
Pluto was reclassified as a "dwarf planet" by the International Astronomical Union (IAU) in 2006. This decision was based on the introduction of a formal definition of what constitutes a planet, which Pluto did not fully meet. Since then, it has been referred to as a "dwarf planet" rather than a "plutiod." The term "plutiod" is used to describe a category of objects similar to Pluto, but it is not the classification of Pluto itself.
Some notable events in 2006 include the launch of Twitter, Google buying YouTube, the release of the Nintendo Wii, and the discovery of the dwarf planet Eris. It was also the year that Pluto was reclassified as a dwarf planet.
Scientists concluded that Pluto is to small to be a normal planet. It is more of a ball of ice. I think this was established in 2008.

2006
The thinking today is that the planet Pluto is no longer a planet, but is now considered a dwarf, from the year 2006.
The dwarf planet, Pluto, has a year of 247.9 Earth years.
Some notable events in 2006 include the launch of Twitter, Google buying YouTube, the release of the Nintendo Wii, and the discovery of the dwarf planet Eris. It was also the year that Pluto was reclassified as a dwarf planet.
The dwarf planet Pluto is the planet with a year 248 earth years long.
The dwarf planet Pluto was discovered in the year 1930. It was discovered by Clyde Tombaugh and is the largest object found in the Kuiper belt.
