Mars and Uranus will share the same right ascension, with Mars passing 39' to the south of Uranus.
From South El Monte , the pair will become visible at around 17:48 (PDT), 28° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 20:44.
Mars will be at mag 0.9, and Uranus at mag 5.9, both in the constellation Capricornus.
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 | 21h06m30s | 17°55'S | Capricornus | 0.9 | 5"3 |
| Uranus | 21h06m30s | 17°16'S | Capricornus | 5.9 | 3"4 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 52° from the Sun, which is in Ophiuchus at this time of year.
