Venus's 225-day orbit around the Sun will carry it to its furthest point to the Sun – its aphelion – at a distance of 0.73 AU.

In practice, however, Venus's orbit is very close to circular; its distance from the Sun varies by only about 1.5% between perihelion and aphelion. This makes Venus's orbit more perfectly circular than that of any of the Solar System's other planets. As a result, its surface receives almost exactly the same amount of energy from the Sun at perihelion (closest approach to the Sun) and aphelion (furthest recess from the Sun).

The exact position of Venus at the moment it passes aphelion will be:

Object Right Ascension Declination Constellation Angular Size
Venus 02h19m20s +11°09' Aries 21.5"
Sun 05h24m +23°11' Taurus 31'29"

The coordinates above are given in J2000.0.

From Fairfield, Venus will be difficult to observe as it will appear no higher than 19° above the horizon. It will be visible in the dawn sky, rising at 03:05 (EDT) – 2 hours and 16 minutes before the Sun – and reaching an altitude of 19° above the eastern horizon before fading from view as dawn breaks around 04:59.

The circumstances of this event were computed using the DE405 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.
