Is Pluto a planet? Does it qualify? For an object to be a planet, it needs to meet these three requirements defined by the IAU:
1. It needs to be in orbit around the Sun – Yes, so maybe Pluto is a planet.
2. It needs to have enough gravity to pull itself into a spherical shape – Pluto…check
3. It needs to have “cleared the neighborhood” of its orbit – Uh oh. Here’s the rule breaker. According to this, Pluto is not a planet.
My teacher taught me this so I guess Pluto is definitely NOT a planet.

a sphere doesnt mean its completely circular. the poles are flat and at the equator they buldge.
