Mars and Uranus will share the same right ascension, with Mars passing 3°11' to the south of Uranus.
From Fairfield , the pair will be visible in the dawn sky, rising at 23:56 (EDT) and reaching an altitude of 33° above the south-eastern horizon before fading from view as dawn breaks at around 03:53.
Mars will be at mag -1.2, and Uranus at mag 5.8, both in the constellation Aquarius.
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 Mars 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 |
| Mars | 22h19m40s | 14°24'S | Aquarius | -1.2 | 15"0 |
| Uranus | 22h19m40s | 11°13'S | Aquarius | 5.8 | 3"6 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 117° from the Sun, which is in Taurus at this time of year.
