Why does Aristarchus theory of the sun is much larger than Earth support the heliocentric theory of the solar system?
According to modern understanding, the planets, and the Sun, move around the Solar System's center of mass. Since the Sun is much more massive than the planets, this center of mass is very close to the Sun.
If the Sun is much larger than any of the planets, it seems likely that it also has a greater mass - assuming that their respective densities are somewhat similar. And indeed, this is the case here.
