Conjunction of Mercury and Uranus

Mercury and Uranus will share the same right ascension, with Mercury passing 1°14' to the south of Uranus.

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.

Mercury will be at mag 1.1, and Uranus at mag 5.6, 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 through a pair of binoculars.

A graph of the angular separation between Mercury and Uranus 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
Mercury 07h56m30s 20°01'N Gemini 1.1 9"5
Uranus 07h56m30s 21°15'N Gemini 5.6 3"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 23° from the Sun, which is in Gemini at this time of year.
