Mars and Uranus will share the same right ascension, with Mars passing 39' to the north of Uranus.
From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 5° above the horizon at dusk.
Mars will be at mag 1.8, and Uranus at mag 5.6, both in the constellation Cancer.
The pair will be a little too widely separated to fit comfortably 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 | 08h34m10s | 20°00'N | Cancer | 1.8 | 3"7 |
| Uranus | 08h34m10s | 19°20'N | Cancer | 5.6 | 3"6 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 27° from the Sun, which is in Gemini at this time of year.
