Explain why parallax was a problem in proving the heliocentric model of the solar system.

Parallax was the solution to proving the heliocentric model

the idea goes that if we were at the center of the universe, the stars would not move over the course of a year. the heliocentric model explains star parallax, that stars change position in the sky over time and return to their original spot after a year
