The Moon, Mars and Uranus will make a close approach, passing within 7°57' of each other. The Moon will be 19 days old.
From South El Monte , the trio will be visible in the morning sky, becoming accessible around 23:06, when they reach an altitude of 9° above your eastern horizon. They will then reach their highest point in the sky at 04:02, 50° above your southern horizon. They will be lost to dawn twilight around 06:10, 39° above your south-western horizon.
The Moon will be at mag -12.2; Mars will be at mag 0.0; and Uranus will be at mag 5.4. The trio will lie in the constellation Virgo.
They will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
At around the same time, the trio will also share the same right ascension – called a conjunction.
A graph of the angular separation between the Moon and Mars around the time of closest approach is available here.
The positions of the trio at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 13h09m40s | 13°03'S | Virgo | -12.2 | 29'30"7 |
| Mars | 13h22m00s | 5°41'S | Virgo | 0.0 | 9"6 |
| Uranus | 13h09m50s | 6°42'S | Virgo | 5.4 | 3"9 |
The coordinates above are given in J2000.0. The trio will be at an angular separation of 116° from the Sun, which is in Capricornus at this time of year.
