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 16h56m40s 24°21'S Ophiuchus 14.0"
Sun 14h23m -14°14' Libra 32'13"

The coordinates above are given in J2000.0.

From Cambridge, Venus will become visible around 17:57 (EDT), 12° above your south-western horizon, as dusk fades to darkness. It will then sink towards the horizon, setting 1 hour and 47 minutes after the Sun at 19:28.

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.
