I am specifically referring to the extremes of orbits, since they aint ever circular.

AU = Astronomical unit. 1 AU = 93 million miles. This is the Earths average distance from the Sun.

Pluto aphelion is about 50. Its perihelion is slightly less than Neptunes at about 29. Thats a total of more than 20 times the Earth-Sun distance in the variation of its orbit. A good subject for a new thread that. However the equivalent for a moon is called an Apogee for the furthest point and a Perigee for the closest point to its parent planet.

Whats wrong with a moon having an aphelion rather than an apogee!? For fudge sake. Why have 2 words that mean the same thing. Fillin the universe up with dictionaries.

Seriously tho, why?

Also the word Barycentre causes instant cancer of the genitals by the way.
