Kepler's First Law

Kepler's First Law states that planets orbit the Sun in oval-shaped paths called ellipses, not perfect circles. In these ellipses, the Sun sits at one focus, meaning the distance between the planet and the Sun varies throughout its orbit. This explains why sometimes planets are closer or farther from the Sun, affecting their speed. The law reveals that planetary orbits are predictable and governed by gravity, shaping our understanding of how celestial bodies move in space.
