Celestial Mechanics and Eclipses

Newton and Kepler’s laws of planetary motions.

An introduction to the trajectories of planets in the solar system, and study of the phenomenon named Eclipses through theory, examples and exercises.

In this exercise you will learn about the geometric theory behind the Sun-Earth-Moon system and become acquainted with Kelper’s three laws of planetary motions, furthermore you will learn about a solar and lunar eclipse through a combination of theory and exercises. We will be building upon the background knowledge you already have from high school physics and mathematics such as circular motions, Newton’s laws of motion and a general knowledge of the near solar system.

You will also get the opportunity to work with data, from online data bases, of specific eclipses.

Why investigate celestial mechanics?

In our everyday life we use phones, GPSs, computers, TVs etc. Most of this data transmission would not be possible without our Earth orbiting satellites. Many satellites also monitor the magnetic field, gravity field and the topography of Earth, and have played a vital part in the research of climate change.

Now, to plan and utilise a satellite mission one needs to know of the trajectories of planets and moons. The mechanics behind a satellite’s path around the Earth are the same celestial mechanics that apply to a moon orbiting a planet. Knowledge of celestial mechanics is essential to our understanding of the solarsystem and it helps us predict phenomenons such as solar or lunar eclipses.
