Venus and Mercury will share the same right ascension, with Venus passing 1°12' to the south of Mercury.
From Cambridge , the pair will be difficult to observe as they will appear no higher than 10° above the horizon. They will be visible in the dawn sky, rising at 05:25 (EDT) – 1 hour and 41 minutes before the Sun – and reaching an altitude of 10° above the south-eastern horizon before fading from view as dawn breaks at around 06:38.
Venus will be at mag -3.9, and Mercury at mag -0.4, both in the constellation Scorpius.
The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.
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 | 16h20m30s | 20°26'S | Scorpius | -3.9 | 10"8 |
| Mercury | 16h20m30s | 19°14'S | Scorpius | -0.4 | 6"6 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 21° from the Sun, which is in Sagittarius at this time of year.
