The planets Jupiter and Mars will make a close approach, passing within a mere 46.4 arcminutes of each other.
From South El Monte , the pair will be visible in the dawn sky, rising at 02:25 (PDT) – 3 hours and 7 minutes before the Sun – and reaching an altitude of 25° above the south-eastern horizon before fading from view as dawn breaks at around 04:59.
Jupiter will be at mag -2.2; and Mars will be at mag 0.8. Both objects will lie in the constellation Capricornus.
They 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.
At around the same time, the pair will also share the same right ascension – called a conjunction.
A graph of the angular separation between Jupiter and Mars around the time of closest approach is available here.
The positions of the pair at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| Jupiter | 20h42m50s | 18°34'S | Capricornus | -2.2 | 35"6 |
| Mars | 20h43m40s | 19°19'S | Capricornus | 0.8 | 6"3 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 69° from the Sun, which is in Pisces at this time of year.
