Saturn's 29.5-year orbit around the Sun will carry it to its furthest point to the Sun – its aphelion – at a distance of 10.04 AU.
In practice, however, Saturn's orbit is very close to circular; its distance from the Sun only varies by about 11.5% between perihelion and aphelion. This means that the difference in the amount of heat and light it receives from the Sun between aphelion and perihelion is extremely small.
Finding Saturn
Saturn's distance from the Sun doesn't affect its appearance. From Fairfield, at the moment of aphelion it will become visible at around 19:55 (EDT), 26° above your southern horizon, as dusk fades to darkness. It will then sink towards the horizon, setting at 00:25.
A chart of the path of Saturn across the sky in 1988 can be found here, and a chart of its rising and setting times here.
The position of Saturn at the moment it passes aphelion will be:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| Saturn | 17h43m00s | 22°25'S | Ophiuchus | 0.2 | 17.1" |
The coordinates above are given in J2000.0.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
