Answer 1

Pluto is considered as a dwarf planet.

The three criteria of the IAU for a full-sized planet are:

• It is in orbit around the Sun.
• It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape).
• It has "cleared the neighborhood" around its orbit.

Pluto, shares its orbital neighborhood with Kuiper belt objects such as the plutinos.

This is the reason for considering Pluto, a dwarf planet
