Who is Kepler A German Mathematician who first proposed the three laws of celestial Motion.
inertia The tendency of all objects in the universe to remain at rest if initially at rest.
Ecliptical The apparent path of the sun among the stars.
Equinox either of two days during a year when the sun's noon position is directly above the equator.
