Every moving body circulating regularly around another, describes an ellipse.

Science has proved this incontestably.

The satellites describe ellipses around the planets, the planets around the Sun, the Sun himself describes an ellipse around the unknown star that serves as a pivot for our whole solar system.

How can our Baltimore Gun Club Projectile then escape the universal law?
"Now what is the consequence of this law?
If the orbit were a _circle_, the satellite would always preserve the same distance from its primary, and its velocity should therefore be constant.

But the orbit being an _ellipse_, and the attracting body always occupying one of the foci, the satellite must evidently lie nearer to this focus in one part of its orbit than in another.
