Mars and Uranus will share the same right ascension, with Mars passing 40" to the north of Uranus.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From Los Angeles , the pair will be visible in the dawn sky, rising at 02:53 (PDT) – 3 hours and 37 minutes before the Sun – and reaching an altitude of 23° above the south-eastern horizon before fading from view as dawn breaks at around 05:30.
Mars will be at mag 1.1, and Uranus at mag 5.7, both in the constellation Sagittarius.
The pair will be close enough to fit within the field of view of a telescope, but will also 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 | 18h02m00s | 23°36'S | Sagittarius | 1.1 | 5"4 |
| Uranus | 18h02m00s | 23°37'S | Sagittarius | 5.7 | 3"5 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 63° from the Sun, which is in Aquarius at this time of year.
