What does Kepler's First Law state about elliptic orbits?
- A Planets orbit in circles
- B Planets orbit in ellipses with the sun at the center
- C Planets orbit in ellipses with the sun at a focus
- D Planets' orbits do not change
That's Correct!
It's Wrong!
Kepler's First Law, the Law of Ellipses, states that all planets move in elliptical orbits with the Sun at one of the foci, not the geometric center. This positioning of the Sun at a focus, rather than at the center, introduces asymmetry in orbital dynamics, where the distance between a planet and the Sun varies throughout the orbit, influencing seasonal and temperature variations on planets.
