Activity 3

Here, only one planet shares the same sun with the Earth. The Earth remains unchanged, while you can adjust the parameters of this planet's orbit: Apoapsis (a+c) and Foci distance(2c).just slide the control bars a little to feel the changes in the orbit. Now let's use the sliders to understand how a, b, and c affect the ellipse. Have fun!
Upgrade: - Terms renamed - Earth and Planet positions related to vernal equinox - Description of terms added

Task1:

Given , find a, c; set sliders (Foci distance?, Apoapsis?) to verify orbits of the planets.

Task2:

Set Foci distance=4 and Apoapsis=7 , calculate b and write the equation.
