Which observations support our current idea that the planets move in elliptical orbits around the Sun?
Retrograde Motion: Planets sometimes appear to move backward (retrograde motion) in the night sky.
Brightness Variations: Changes in a planet’s brightness correspond to varying distances from Earth.
Kepler’s Laws: Johannes Kepler formulated laws describing planetary orbits as ellipses, providing a more accurate model.
Equal Areas in Equal Time: Kepler’s second law explains varying planet speeds in their orbits, consistent with elliptical paths.
Harmonic Law: Kepler’s third law establishes a relationship between orbital periods and average distances from the Sun.
Telescope Observations: Telescopes enabled detailed observations supporting Kepler’s laws and the concept of elliptical orbits.
