What is the HELIOCENTRIC model of the solar system?

The heliocentric model of the solar system is the one that suggests that the sun is in the center of the universe and everything revolves around it.

Explanation:

There have been few models throughout history when it comes to the arrangement and hierarchy of the objects in space. Most of them have been wrong, though they have persisted for a very long time. Some, like the heliocentric model, got some basics right, but it still had some mistakes which from today's perspective are big ones.

The heliocentric model suggests that the Sun is the center of the universe, with all other objects in space orbiting around it. Now, it did guess right that the planets in the solar system revolve around it and that it is in the center of it, but it made a big mistake by putting the Sun in the center of the universe, not just the solar system. Not just that the Sun is not in the center of the universe, it is not even close to the center of the galaxy in which it is, nor it is the largest object or the one with the biggest gravity so that it attracts everything around to revolve around it.
