Saturn and Mars will share the same right ascension, with Saturn passing 2°02' to the south of Mars.
From South El Monte , the pair will become visible at around 18:31 (PDT), 18° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 9 minutes after the Sun at 20:02.
Saturn will be at mag 0.7 in the constellation Cetus, and Mars at mag 1.3 in the neighbouring constellation of Pisces.
The pair will be too widely separated to fit 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 Saturn 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 |
| Saturn | 00h47m10s | 2°37'N | Cetus | 0.7 | 16"1 |
| Mars | 00h47m10s | 4°40'N | Pisces | 1.3 | 4"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 27° from the Sun, which is in Aquarius at this time of year.
