# A planet of constant mass orbits the sun in an elliptical orbit. Neglecting any friction effects, what happens to the planet’s rotational kinetic energy about the sun’s center?

A planet of constant mass orbits the sun in an elliptical orbit. Neglecting any friction effects, what happens to the planet’s rotational kinetic energy about the sun’s center?

- **A.** It remains constant.
- **B.** It decreases continually.
- **C.** It increases continually.
- **D.** It decreases when the planet approaches the sun, and increases when it moves farther away.
- **E.** It increases when the planet approaches the sun, and decreases when it moves farther away.
