Venus and Mercury will share the same right ascension, with Venus passing 5°15' to the north of Mercury.
From Cambridge however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 2° above the horizon at dusk.
Venus will be at mag -3.9, and Mercury at mag 0.7, both in the constellation Virgo.
The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
A graph of the angular separation between Venus and Mercury around the time of closest approach is available here.
The positions of the two objects at the moment of conjunction will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| Venus | 11h48m00s | 2°35'N | Virgo | -3.9 | 10"7 |
| Mercury | 11h48m00s | 2°40'S | Virgo | 0.7 | 8"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 22° from the Sun, which is in Leo at this time of year.
