Venus and Mercury will share the same right ascension, with Venus passing 6°04' to the south of Mercury.
From Cambridge however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 12° from it.
Venus will be at mag -4.1 in the constellation Hydra, and Mercury at mag 2.4 in the neighbouring constellation of Leo.
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 | 09h39m50s | 5°05'N | Hydra | -4.1 | 57"0 |
| Mercury | 09h39m50s | 11°09'N | Leo | 2.4 | 9"5 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 12° from the Sun, which is in Leo at this time of year.

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.
