Planet?

    Today we were told why Pluto is no longer a planet. For Pluto to be a planet, it has to, 1. orbit a star. 2. have enough gravitational pull to control objects in its neighborhood meaning that it has a clear orbit, 3. it has to be spherical. Pluto orbits the sun, which is a star. so maybe it is a planet. Pluto has enough gravitational pull to be in a spherical shape. But Pluto does not have a "clear neighborhood" of it's orbit. So it is not a planet.
     My body, Miranda a moon of Uranus, is not a planet. My body doesn't orbit a star, or have a gravitational pull that it is spherical.


INTRESTING FACT: Gerald Kuiper who discovered Miranda. The Kuiper Belt was named after him.
