Solve the problem.The orbit of a planet around a sun is an ellipse with the sun at one focus. The aphelion of a planet is its greatest distance from the sun, its perihelion is its shortest distance, and its mean distance is the length of the semimajor axis of the elliptical orbit. If a (hypothetical) planet has a perihelion of 431.4 million miles and a mean distance of 434 million miles, write an equation for the orbit of the planet around the sun.
