Students working on astronomy science fair projects can benefit from learning the basic theories behind the science of astronomy like Kepler's first law. This law state is based on the assumption that planetary orbits are ellipses and that the sun provides one of the elliptical foci.
Kepler's 1st Law: The orbits of the planets are ellipses. the sun is at one focus of the eclipse.
Kepler's 2nd Law: The imaginary line that or distance between the planets and the sun stay equal distance as a planet travels around the eclipse.
Investigate and find out what the 3rd law is -:0)
