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 21h46m10s -14°42' Capricornus 9.9"
Sun 22h18m -10°32' Aquarius 32'20"

The coordinates above are given in J2000.0.

From Cambridge, Venus will not be observable – it will reach its highest point in the sky during daytime and will be 1° below the horizon at dawn.

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.

Source

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.
