No. There are almost no astronomers that think Pluto is a planet. They know it's officially a dwarf planet.
No. Most follow the new IAU definition of a planet which excludes Pluto.
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.
the planet because Pluto the planet was there before all of us
Pluto was considered a planet until fairly recently. It has now been established as belonging to the kuiper belt, rather than our solar system - and thus has been 'downgraded' to a dwarf planet.
No, they are not. Pluto doesn't meet all of the requirements to be considered a planet.
First of all, Pluto is not a planet. It was considered a double planet because its largest moon Charon is half its size.
Depends whether you include Pluto as a planet or not (I think it isn't at the moment - but it does seem to swap back and forth!). So, if you include Pluto, then it's Pluto. If you include all the dwarf planets (of which Pluto is one) - then its Eris. Otherwise, it's Neptune
No, mercury is. Pluto is a dwarf planet because it does not meet all the criteria to be a planet and it is the second largest dwarf planet so far.
Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union because it did not meet all the criteria to be considered a full planet. One of the criteria is that a planet must clear its orbit of other debris, which Pluto did not do.
all i know that planet x is past Pluto
Pluto was reclassified as a dwarf planet on August 24, 2006, by the International Astronomical Union. This decision was made because Pluto did not meet all the criteria necessary to be considered a full-fledged planet.
