Which statement describes a planet as it moves along its orbit?

Answer:

D. It travels fastest and Stronger gravitational pull when closer to sun.

Explanation:

The statement which describes a planet as it moves along its orbit is: D. It travels fastest and experiences a stronger gravitational pull when it is closest to the sun.

A planet can be defined as a large astronomical (celestial) body that has sufficient mass to allow for self-gravity and make it assume a nearly circular shape, which is known as hydrostatic equilibrium.

Generally, a planet revolves in its orbit around the Sun in the solar system and it has a cleared neighborhood.

In conclusion, when a planet is closest to the Sun, it travels fastest and experiences a stronger gravitational pull as it move along its orbit.
