28 de may. de 2024 · Kepler’s laws of planetary motion, in astronomy and classical physics, laws describing the motion of planets in the solar system. They were derived by the German astronomer Johannes Kepler, who announced his first two laws in the year 1609 and a third law nearly a decade later, in 1618.

- Kepler’s first law means that planets move around the Sun in elliptical orbits. An ellipse is a shape that resembles a flattened circle. How much t...
- The eccentricity of an ellipse measures how flattened a circle it is. It is equal to the square root of [1 - b*b/(a*a)]. The letter a stands for th...
- How long a planet takes to go around the Sun (its period, P) is related to the planet’s mean distance from the Sun (d). That is, the square of the...
- A planet moves slower when it is farther from the Sun because its angular momentum does not change. For a circular orbit, the angular momentum is e...
- It follows from Kepler’s second law that Earth moves the fastest when it is closest to the Sun. This happens in early January, when Earth is about...
Hace 2 días · In astronomy, Kepler's laws of planetary motion, published by Johannes Kepler between 1609 and 1619, describe the orbits of planets around the Sun. The laws modified the heliocentric theory of Nicolaus Copernicus, replacing its circular orbits and epicycles with elliptical trajectories, and explaining how planetary velocities vary.
