Question

who rediscovered aristarchuss model of a heliocentric solar system? copernicus galileo kepler ptolemy

Explanation:

Aristarchus proposed a heliocentric model around 270 BCE, but it was not widely accepted. Copernicus, in the 16th century, independently developed a heliocentric model. His work "On the Revolutions of the Heavenly Spheres" (1543) presented a detailed heliocentric system. Galileo supported the heliocentric model through his observations (e.g., phases of Venus), but he did not rediscover the model. Kepler further refined the heliocentric model with his laws of planetary motion. Ptolemy proposed a geocentric model.

Copernicus
