Astronomy: Kepler’s Laws

Kepler’s First Law: Law of Orbit

All things orbit in the shape of an ellipse and goes around two focui one being the sun/star.

Kepler’s Second Law: Law of Equal Areas

Things move faster when closer to the sun which is called Perihelion. Things move slower the farther away they are from the sun called Aphelion.

Kepler’s Third Law: Law of Harmony

The amount of time it takes to orbit is dependent on the size of the orbit/ellipse.

Extra Notes:

Things in an orbit will take the same amount of time. But different orbits will take different amounts of time.
