Conversely, aphelion happens at the apoapsis, the farthest reaches of the ellipse. Comets, for instance, provide the most striking examples of the perihelion-aphelion cycle.

Therefore, the physical distance is only one variable in a much more complex equation involving radiation and atmospheric dynamics. A comet might spend centuries or even millennia in the distant, cold reaches of the Oort Cloud, moving slowly at aphelion.
Observing the Phenomenon For the amateur astronomer, the concepts of aphelion and perihelion offer a practical framework for observation. The Science of the Orbit: Defining the Extremes To understand the mechanics of these points, one must first look at the shape of the trajectory.

A line connecting the planet or comet to the sun sweeps out equal areas in equal times, meaning the object must move much faster at perihelion than at aphelion. Although the size change of the sun or moon is imperceptible to the naked eye, the timing of these events influences tidal forces and satellite operations.
