planetary movements

Planetary movements are governed by gravity and the laws of physics, causing planets to orbit the Sun in elliptical paths. Each planet’s speed varies: they move faster when closer to the Sun (perihelion) and slower when farther away (aphelion). These orbits are stable over long periods, maintained by the balance between the planet’s forward motion and the Sun’s gravitational pull. As planets orbit, they also rotate on their axes at different rates. This combined motion results in the regular progression of day and night, seasons, and the apparent movement of planets across the sky from our perspective on Earth.
