1. The problem statement, all variables and given/known data

Consider the motion of an object between a point close to the planet and a point very very far from the planet.
Indicate whether the following statements are true or false

Angular momentum about the center of the planet is conserved.

2. Relevant equations

?

3. The attempt at a solution

I am not sure what is meant.

I don't want to just guess. any help/hint.

I would like to solve mathematically but also verbally as well.

The angular moment changes when a torque acts on a body. In this case, throughout the motion of the object the line of the force is passing though the center of the planet.
Now, what is your conclusion?

No. It is true. Because there is no torque acting on the planet.
