What is helocentrism?

Answer 1

The theory that the Sun is in the center, and the planets orbit around it.

Answer 2

Heliocentrism is the astronomical model that places the Sun at the center of the solar system, with the planets, including Earth, orbiting around it. This model was proposed by Copernicus in the 16th century, challenging the previously accepted geocentric model where Earth was considered the center of the universe. The acceptance of heliocentrism revolutionized our understanding of the cosmos.
