Venus and Mercury will share the same right ascension, with Venus passing 53' to the north of Mercury.
From Cambridge , the pair will be difficult to observe as they will appear no higher than 11° above the horizon. They will become visible at around 20:31 (EST), 11° above your north-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 40 minutes after the Sun at 21:46.
Venus will be at mag -4.2, and Mercury at mag -0.6, both in the constellation Taurus.
The pair will be a little too widely separated to fit comfortably 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 | 05h15m00s | 26°08'N | Taurus | -4.2 | 53"5 |
| Mercury | 05h15m00s | 25°14'N | Taurus | -0.6 | 6"1 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 18° from the Sun, which is in Taurus at this time of year.

Warning
Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
