Relationship to Speed: When a planet is closer to the Sun (near perihelion), it must move faster to sweep out the same area in a given time as when it is farther from the Sun (near aphelion).

When the phrase "two spacecraft are following paths in space given by" is used, it implies that we have access to this kind of information for both spacecraft, usually in the form of mathematical ...
