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 position of Venus at the moment it passes aphelion will be:
| Object | Right Ascension | Declination | Constellation | Angular Size |
| Venus | 20h36m10s | 19°48'S | Capricornus | 9.8" |
| Sun | 20h21m | 19°28'S | Capricornus | 32'29" |
The coordinates above are given in J2000.0.
From Cambridge, Venus will not be readily observable since it will be very close to the Sun, at a separation of only 3° from it.

Warning
Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.

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.
