The Moon, Saturn and Mars will make a close approach, passing within 6°56' of each other. The Moon will be 4 days old.
From Cambridge , the trio will become visible at around 19:07 (EDT), 16° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 21 minutes after the Sun at 20:55.
The Moon will be at mag -10.8; Saturn will be at mag 0.4; and Mars will be at mag 1.1. The trio will lie in the constellation Libra.
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 Saturn 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 | 15h27m40s | 24°03'S | Libra | -10.8 | 30'12"4 |
| Saturn | 15h35m30s | 17°21'S | Libra | 0.4 | 15"7 |
| Mars | 15h29m50s | 19°55'S | Libra | 1.1 | 5"0 |
The coordinates above are given in J2000.0. The trio will be at an angular separation of 53° from the Sun, which is in Virgo at this time of year.
