Venus's 225-day orbit around the Sun will carry it to its closest point to the Sun – its perihelion – at a distance of 0.72 AU from the Sun.

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 perihelion will be:

Object Right Ascension Declination Constellation Angular Size
Venus 00h30m10s +08°38' Pisces 41.2"
Sun 22h16m -10°45' Aquarius 32'20"

The coordinates above are given in J2000.0.

From Fairfield, Venus will become visible around 17:50 (EST) as the dusk sky fades, 33° above your western horizon. It will then sink towards the horizon, setting 3 hours and 23 minutes after the Sun at 20:54.

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.
