Pluto no longer qualifies as a planet. There is certain criteria that has to be met in order for a planet to be considered a planet. 1. it must orbit the sun 2. it’s own gravity has to be enough to cause its shape to remain spherical 3. “It should be the biggest, most gravitationally dominant planet in its own orbit” (Kulkarni, 2010). Sadly, Pluto fails the third criterion
No, it didn’t meet the third criteria for being considered a planet, as meg said.
No, but it is considered a dwarf planet because it:
(a) is in orbit around the Sun
(b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape
(c) has not cleared the neighborhood around its orbit
(d) is not a satellite
