The Moon, Saturn and Mars will make a close approach, passing within 3°07' of each other. The Moon will be 3 days old.

From Fairfield , the trio will become visible at around 21:10 (EDT), 20° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 36 minutes after the Sun at 23:05.

The Moon will be at mag -10.8; Saturn will be at mag 0.6; and Mars will be at mag 1.7. The trio 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 trio 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 trio at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 10h23m50s 8°28'N Leo -10.8 31'36"8
Saturn 10h29m30s 11°16'N Leo 0.6 16"7
Mars 10h21m00s 11°26'N Leo 1.7 4"3

The coordinates above are given in J2000.0. The trio will be at an angular separation of 49° 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.
