• Examples of SDLC mo

The orbit of a planet is an ellipse with the sun at one of the foci.

• An ellipse is a closed curve with two foci.

• The sun is located at one of the foci of a planet's elliptical orbit.

• The shape of the orbit affects the planet's distance from the sun over time.

• Kepler's laws of planetary motion describe the elliptical nature of orbits.
