Why do peoplel say Pluto isn't planet?

Answer 1

Pluto is not considered a planet anymore mainly due to its size, orbit, and its location in the atmosphere. As telescopes got more advanced, scientists started to see many more objects in our solar system that resembled Pluto. Pluto is one of the smallest objects (not including asteriods or comets) in the solar system, its orbit is not like the rest of the planets (it orbits more like the asteriods in the outer belt), and Pluto is located in the outer-belt, which means it has not "cleared its pathway".

Answer 2

Pluto was discovered in 1930.it was considered as a planet till 2006.

it was then put into the category called dwarf planet . there are some conditions of something to be a planet.

they are the following:

1. a planet must be round, pulled into that shape by its gravity.

2. a planet must orbit a star.

3. a planet must have cleared its neighbourhood of its orbit. it means that as a planet travels, its gravity sweeps the space around it and does not allow any other objest to cross its orbit.

now Pluto is a dwarf planet as it does not follow the third rule.

Answer 3

Pluto is a planet, but it only too small, so they took it away, eg if it have nine human ( one is 60 years old, one is 40, the other is 30 etc,, till you reach to a baby which is 1/2 years old),, you can't deny the baby as not human because he/she's too small,, he's/she's human no matter how small he/she is,, this is the same as pluto,, pluto is a planet but since it's size is too small,, the scientitif process remove it as a planet.

Answer 4

Pluto was reclassified as a dwarf planet because it did not meet all the criteria set by the International Astronomical Union for a planet. Specifically, Pluto has not cleared its orbit of other debris and is located within a zone of similar objects in the Kuiper Belt. Due to these reasons, it is classified as a dwarf planet rather than a full-fledged planet.
