The orbit of a planet around its star is an ellipse, with the star at one focus. The apoapsis of a planet is its greatest distance from the star, and the periapsis is its shortest distance. Its mean distance is the length of the semimajor axis. The mean distance from a planet to its star is93 million miles. If the apoapsis of the planet is98 million miles, what is the periapsis? Write an equation for the orbit of the planet around the star. The periapsis is million miles.
