The Moon and Saturn will make a close approach, passing within 4°01' of each other. The Moon will be 19 days old.
From Cambridge , the pair will be visible in the dawn sky, rising at 23:38 (EST) and reaching an altitude of 32° above the southern horizon before fading from view as dawn breaks at around 04:22.
The Moon will be at mag -12.4; and Saturn will be at mag 0.5. Both objects will lie in the constellation Capricornus.
They 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.
At around the same time, the pair 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 pair at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 21h55m40s | 18°07'S | Capricornus | -12.4 | 32'24"5 |
| Saturn | 21h49m50s | 14°21'S | Capricornus | 0.5 | 17"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 122° from the Sun, which is in Taurus at this time of year.
