Astronomical Observations
Observations of planetary movements over time demonstrate the consistent patterns that align with the heliocentric model. For example, the retrograde motion of planets like Mars can be explained by the relative positions of Earth and Mars in their orbits around the Sun.
Gravitational Interactions
The gravitational pull exerted by the Sun on the planets, including Earth, plays a crucial role in maintaining their orbital paths. Newton's law of universal gravitation provides a mathematical framework for understanding these interactions.

Geocentric Model
In the geocentric model, Earth is considered to be the stationary center of the universe, with celestial bodies, including the Sun, Moon, and planets, revolving around it. This view dominated ancient astronomy.

Shift in Paradigm
The heliocentric model represented a significant shift from the geocentric view that placed Earth at the center of the universe. It led to a reevaluation of existing astronomical theories and paved the way for a more accurate understanding of planetary motion.

Historical Context
The belief in the Earth orbiting the Sun traces back to the scientific revolution in the 16th century. During this period, astronomers like Copernicus and Galileo proposed the heliocentric model, which suggested that the Earth revolves around the Sun. This model gained acceptance due to observational evidence and mathematical calculations.
