Venus and Mercury will share the same right ascension, with Venus passing 4°22' to the south of Mercury.
From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be 0° below the horizon at dusk.
Venus will be at mag -4.5, and Mercury at mag -0.1, both in the constellation Libra.
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 | 15h03m40s | 24°29'S | Libra | -4.5 | 52"6 |
| Mercury | 15h03m40s | 20°06'S | Libra | -0.1 | 6"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 26° from the Sun, which is in Virgo at this time of year.
