A flat planet, for the purpose of this theory, is defined as a celestial body with a predominantly planar surface, lacking the spherical or elliptical shape commonly associated with celestial bodies.
There is no north nor south pole, but instead, a massive ice belt that surrounds the Earth's disc. This belt contains our oceans and keep us locked.
Planetary formation usually involves the aggregation of material from an accretion disk around a young star. It is conceivable that under certain conditions, remnants of this disk could evolve into large, flat structures rather than the typical spherical ones.
Massive collisions between proto-planets or between a proto-planet and an asteroid could potentially result in a planar fragment being ejected and later stabilizing into a flat planet.
