The Moon, Mars and Uranus will make a close approach, passing within 5°40' of each other. The Moon will be 6 days old.
From Fairfield , the trio will become visible at around 17:59 (EST), 51° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 22:53.
The Moon will be at mag -11.3 in Pisces; Mars will be at mag 1.0 in Pisces; and Uranus will be at mag 5.8 in Aries.
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 | 01h48m50s | 5°37'N | Pisces | -11.3 | 30'11"9 |
| Mars | 01h40m40s | 10°55'N | Pisces | 1.0 | 5"8 |
| Uranus | 01h48m00s | 10°35'N | Aries | 5.8 | 3"4 |
The coordinates above are given in J2000.0. The trio will be at an angular separation of 65° from the Sun, which is in Capricornus at this time of year.
