The Moon and Saturn will share the same right ascension, with the Moon passing 1°09' to the south of Saturn. The Moon will be 3 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Fairfield , the pair will become visible at around 21:06 (EST), 18° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 24 minutes after the Sun at 22:52.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -10.5, and Saturn at mag 0.3, both in the constellation Cancer.

The pair 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.

A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 09h16m20s 15°46'N Cancer -10.5 32'58"8
Saturn 09h16m20s 16°56'N Cancer 0.3 16"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 41° from the Sun, which is in Gemini 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.
