Chapter 10, Problem 21E

To determine

To Explain: the Eris’s Distance from the sun compared with the assumption produced by the model of exercise 19.

Explanation of Solution

The model projected in exercise 19 that a planet at position 9 had a distance of 4819.48 million miles from the sun. The real distance from Eris, however, is 6300 million miles. Thus, the model assumes a much shorter distance than the real Eris (9 m planet) distance.
