Los vecinos más cercanos de la Tierra: los planetas que giran

The video explores the evolution of astronomical beliefs, highlighting the shift from the geocentric model to Copernicus' heliocentric model. It explains the concept of orbits and the critical role of gravity in maintaining planetary paths. The video discusses the hypothetical scenario of planets without gravity, emphasizing the importance of inertia in planetary motion. Finally, it introduces the concept of ellipses and provides a brief overview of nearby planets.

What would happen to the planets if gravity did not exist?

How do inertia and gravity work together to keep the planets in orbit around the Sun?
