Jupiter and Mars will share the same right ascension, with Jupiter passing 38' to the south of Mars.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From South El Monte , the pair will be difficult to observe as they will appear no higher than 17° above the horizon. They will be visible in the dawn sky, rising at 04:04 (PDT) – 2 hours and 16 minutes before the Sun – and reaching an altitude of 17° above the eastern horizon before fading from view as dawn breaks at around 05:37.
Jupiter will be at mag -1.8, and Mars at mag 1.7, 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 to the naked eye or through a pair of binoculars.
A graph of the angular separation between Jupiter and Mars 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 |
| Jupiter | 09h03m00s | 17°21'N | Cancer | -1.8 | 31"3 |
| Mars | 09h03m00s | 17°59'N | Cancer | 1.7 | 3"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 28° from the Sun, which is in Leo at this time of year.
