Explain how the following terms relate to an ellipse and an elliptic planetary orbit: ‘focus’, ‘eccentricity’, ‘perihelion’, ‘aphelion’.b) Let’s say you know the size and period of the orbit of Moon 1 around a certain planet. You find a Moon 2 with a smaller orbit. Which of Kepler’s laws can you apply to find its period of revolution and explain how you would do it. Would Moon 2’s period be larger or smaller than Moon 1’s?NOT budging on price simple discussion Thanks
