Saturn and Mercury will share the same right ascension, with Saturn passing 2°26' to the south 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 10° above the horizon at dusk.
Saturn will be at mag -0.0, and Mercury at mag 0.1, both in the constellation Gemini.
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 Saturn 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 |
| Saturn | 06h28m50s | 22°42'N | Gemini | -0.0 | 16"7 |
| Mercury | 06h28m50s | 25°09'N | Gemini | 0.1 | 7"5 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 23° from the Sun, which is in Taurus at this time of year.
