Mars and Uranus will share the same right ascension, with Mars passing 1°03' to the north of Uranus.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Washington, the pair will become visible around 18:47 (MST) as the dusk sky fades, 52° above your south-western horizon. They will then sink towards the horizon, setting at 23:23.
Mars will be at mag 1.0, and Uranus at mag 5.8, both in the constellation Aries.
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 | 01h48m20s | +11°40' | Aries | 1.0 | 5"7 |
| Uranus | 01h48m20s | +10°37' | Aries | 5.8 | 3"4 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 64° from the Sun, which is in Capricornus at this time of year.
