Question

which idea was supported by aristarchus, copernicus, and galileo?
the planets have epicycles.
the planets revolve around the sun.
the stars rotate around the sun.
the center of the solar system is earth.

Explanation:

Aristarchus proposed a heliocentric model where planets revolve around the Sun. Copernicus developed the Copernican heliocentric model with planets orbiting the Sun. Galileo's observations (e.g., phases of Venus) supported the heliocentric view. The idea of epicycles was part of the geocentric model (opposite of what these three supported). Stars do not rotate around the Sun - the Sun is part of the Milky Way galaxy with stars in the galaxy having their own orbits. The geocentric model (center of solar system is Earth) was what these three were arguing against.

Answer:

The planets revolve around the Sun.
