Astronomers used to consider that Pluto was a planet and have now stated it is just one of many objects in the Kuiper Belt. The Kuiper Belt is made of the leftovers in the creation of the Solar System.
No, not all astronomers consider Pluto a planet. Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union, leading to debate among scientists about its classification. Some astronomers argue that Pluto does not meet all the criteria to be considered a full planet.
No. Most follow the new IAU definition of a planet which excludes Pluto.

The meeting of astronomers at the International Astronomical Union (IAU) where Pluto was redefined and classified as a "dwarf planet" took place in August 2006. During this meeting, the IAU established new criteria for what constitutes a planet, leading to the conclusion that Pluto did not meet all the necessary requirements due to its size and other factors.
The discovery of Charon, Pluto's largest moon, in 1978 provided crucial insights into Pluto's mass and density, allowing astronomers to determine its size more accurately. By studying the orbital dynamics between Pluto and Charon, scientists could calculate Pluto's gravitational influence, leading to a better understanding of its composition and structure. This discovery also prompted discussions about the classification of celestial bodies in our solar system, contributing to the redefinition of what constitutes a planet. Overall, Charon's presence significantly enhanced our knowledge of the Pluto system and its characteristics.
Astronomers think Pluto is a dwarf planet. And they're right.

No. There are almost no astronomers that think Pluto is a planet. They know it's officially a dwarf planet.
