>if a celestial body is big enough, it becomes a planet
What did nippon mean by this?
Ganymede is a fucking satellite, retard. It orbits Jupiter therefore it's not a planet. Pray tell me what planet does Mercury orbit?
More like Gaymede, am I right lads?
Now this is epiko
Planets are partially defined by their ability to clear their neighbourhood
Isn't that why pluto was disqualified though, it was too small.
Nah, that's not the reason. Official criteria to be a 'full-sized' planet is:
1. It is in orbit around the Sun.
2. It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape).
3. It has “cleared the neighborhood” around its orbit.
Pluto failed on Number 3; because it doesn't have sufficient gravitation force to affect smaller objects in its vicinity, it can't be considered a legitimate planet.
