NOT cleared the neighborhood of its orbit
Is not a satellite

4. Planet In orbit around the sun
Has enough mass that is has a round shape (or almost round)
HAS cleared the neighborhood around its orbit
Is NOT a satellite

5. Asteroid Orbits the Sun inside the orbit of Jupiter
DOES NOT have sufficient mass for it to maintain a round shape (not as round in looks)
HAS NOT cleared the neighborhood around its orbit
Is NOT a satellite
