Officially then, Pluto is no longer a planet
“For an object to be a planet, it needs to meet three requirements defined by the IAU:
(1) The object needs to be in orbit around the Sun – Yes, so maybe Pluto is a planet.
(2) The object needs to have enough gravity to pull itself into a spherical shape – Pluto…check
(3) The object needs to have “cleared the neighborhood” of its orbit
– Uh oh. That was the rule breaker. According to this, Pluto is not a planet”
Amazingly, although Pluto is not a planet, many are unaware of that fact so that is the inspiration for this thread
QUOTE:
“As planets form, they become the dominant gravitational body in their orbit in the Solar System
As planets interact with other, smaller objects, they either consume them, or sling them away with their gravity.
Pluto is only 0.07 times the mass of the other objects in its orbit. The Earth, in comparison, has 1.7 million times the mass of the other objects in its orbit”
