The Moon and Saturn will make a close approach, passing within 4°57' of each other. The Moon will be 24 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 00:53 (EDT) and reaching an altitude of 51° above the south-eastern horizon before fading from view as dawn breaks at around 06:06.

The Moon will be at mag -11.5; and Saturn will be at mag 0.9. Both objects will lie in the constellation Leo.

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 11h17m50s 1°11'N Leo -11.5 30'53"4
Saturn 11h26m50s 5°36'N Leo 0.9 17"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 69° from the Sun, which is in Libra at this time of year.
