The Moon and Saturn will make a close approach, passing within 6°09' of each other. The Moon will be 13 days old.

From Columbus , the pair will be visible in the evening sky, becoming accessible around 21:03 (EDT), 25° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 00:17, 43° above your southern horizon. They will continue to be observable until around 04:56, when they sink below 10° above your western horizon.

The Moon will be at mag -12.7; and Saturn will be at mag 0.3. Both objects will lie in the constellation Virgo.

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 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 13h27m30s 12°49'S Virgo -12.7 33'17"2
Saturn 13h35m00s 6°57'S Virgo 0.3 18"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 160° from the Sun, which is in Aries at this time of year.
