In Problems 79-83, use the fact that the orbit of a planet about the Sun is an ellipse, with the Sun at one focus. The aphelion of a planet is its greatest distance from the Sun, and the perihelion is its shortest distance. The mean distance of a planet from the Sun is the length of the semimajor axis of the elliptical orbit. See the illustration. Earth The mean distance of Earth from the Sun is 93 million miles. If the aphelion of Earth is 94.5 million miles, what is the perihelion? Write an equation for the orbit of Earth around the Sun.

Expert Solution
To determine
To find:
a. The measurement of perihelion, if the aphelion of Earth is miles.
Answer to Problem 79AYU
Solution:
a. Perihilion million miles.
Explanation of Solution
Given:
Use the fact that the orbit of a planet about the Sun is an ellipse, with the Sun at one focus. The aphelion of a planet is its greatest distance from the Sun, and the perihelion is its shortest distance. The mean distance of a planet from the Sun is the length of the semi major axis of the elliptical orbit.
The mean distance of Earth from the Sun is 93 million miles.
Formula used:
Center
Major axis
Foci
Vertices
Equation
Calculation:
Mean distance million miles, Hence million miles.
The length of the major axis: million.
From the figure we see that,
a.
To find:
b. An equation for the orbit of Earth around.
Solution:
b. ( in millions of miles).
