Mars and 136108 Haumea will share the same right ascension, with Mars passing 4°00' to the south of 136108 Haumea.
From South El Monte , the pair will be visible in the dawn sky, rising at 00:34 (PDT) and reaching an altitude of 35° above the southern horizon before fading from view as dawn breaks at around 04:44.
Mars will be at mag -0.5, and 136108 Haumea at mag 16.1, both in the constellation Sagittarius.
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 136108 Haumea 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 | 20h02m40s | 22°08'S | Sagittarius | -0.5 | 11"6 |
| 136108 Haumea | 20h02m40s | 18°08'S | Sagittarius | 16.1 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 109° from the Sun, which is in Aries at this time of year.
