Which of the following correctly characterizes the velocity and angular momentum of a planet orbiting the Sun?
A) The velocity is maximum at aphelion, while the angular momentum is maximum at perihelion.
B) The velocity and angular momentum are both maximum at perihelion.
C) The velocity and angular momentum are constant throughout the orbit.
D) The velocity is maximum at perihelion, while the angular momentum is constant throughout the orbit.

According to Kepler's laws, the planet's velocity is maximum at perihelion (closest point to the Sun) and minimum at aphelion (farthest point from the Sun). However, the angular momentum is constant throughout the orbit, as there is no external torque acting on the system. Therefore, the correct choice is D, which states that the velocity is maximum at perihelion, while the angular momentum is constant throughout the orbit.
