The Moon and Saturn will make a close approach, passing within 3°11' of each other. The Moon will be 26 days old.
From Columbus , the pair will be difficult to observe as they will appear no higher than 13° above the horizon. They will be visible in the dawn sky, rising at 04:54 (EST) – 1 hour and 57 minutes before the Sun – and reaching an altitude of 13° above the south-eastern horizon before fading from view as dawn breaks at around 06:14.
The Moon will be at mag -10.9; and Saturn will be at mag 0.8. Both objects will lie in the constellation Aquarius.
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 | 22h30m30s | 14°16'S | Aquarius | -10.9 | 32'27"3 |
Saturn | 22h25m00s | 11°21'S | Aquarius | 0.8 | 15"9 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 51° from the Sun, which is in Pisces at this time of year.
