¿Por qué los planetas son redondos? ¿Por qué giran los planetas?

The video explains why planets are spherical due to gravity, contrasting this with the shapes of asteroids, which are not influenced by strong gravity. It discusses surface tension and isostatic adjustment, which limit mountain heights. The formation of the solar system is described, highlighting how planets formed from a spinning disk of gas and dust, maintaining rotation due to angular momentum. The video also covers the unique rotation of Venus and Uranus, which differ from other planets due to past collisions or interactions.
