A comet moves on a stretched, elliptical orbit with the Sun at one focus. It speeds up as it swings in close and slows down as it heads out far away. This is energy being swapped: close to the Sun it has lots of kinetic energy, far away it has more gravitational energy. The total stays the same.

At the point you mark, the comet's energy is mostly:
The comet keeps orbiting, fast near the Sun and slow far away. Predict, set the marker, then check.

KE + GPE is constant. Close to the Sun: fast, high KE. Far away: slow, high GPE.
