The Moon and Saturn will make a close approach, passing within 1°32' of each other. The Moon will be 3 days old.

From Fairfield , the pair will be difficult to observe as they will appear no higher than 13° above the horizon. They will become visible at around 19:47 (EDT), 13° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 52 minutes after the Sun at 21:05.

The Moon will be at mag -10.6; and Saturn will be at mag 0.6. Both objects will lie in the constellation Virgo.

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 14h03m50s 8°32'S Virgo -10.6 32'03"0
Saturn 14h01m20s 9°56'S Virgo 0.6 15"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 44° from the Sun, which is in Leo at this time of year.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
