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 | 04h15m40s | 23°09'N | Taurus | 15.6" |
| Sun | 01h35m | 9°58'N | Pisces | 31'52" |
The coordinates above are given in J2000.0.
From Cambridge, Venus will become visible at around 19:43 (EST), 32° above your western horizon, as dusk fades to darkness. It will then sink towards the horizon, setting 3 hours and 31 minutes after the Sun at 22:56.
