The Moon and Mars will make a close approach, passing within 1°07' of each other. The Moon will be 4 days old.

From Cambridge, the pair will be difficult to observe as they will appear no higher than 18° above the horizon. They will become visible around 20:28 (EDT) as the dusk sky fades, 18° above your western horizon. They will then sink towards the horizon, setting 2 hours and 4 minutes after the Sun at 22:11.

The Moon will be at mag -10.6 in Leo; and Mars will be at mag 1.6 in 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 Mars 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 11h36m40s +02°00' Leo -10.6 30'17"2
Mars 11h38m50s +02°59' Virgo 1.6 4"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 48° from the Sun, which is in Cancer at this time of year.

The circumstances of this event were computed using the DE405 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.
