The Moon and Mars will share the same right ascension, with the Moon passing 2°09' to the north of Mars. The Moon will be 7 days old.

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

From Ashburn, the pair will be visible in the evening sky, becoming accessible around 19:54 (EDT) as the dusk sky fades, 74° above your southern horizon. They will then reach its highest point in the sky at 20:02, 74° above your southern horizon. They will continue to be observable until around 02:42, when they sink below 7° above your north-western horizon.

The Moon will be at mag -12.0, and Mars at mag 0.5, both in the constellation Gemini.

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 Mars 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 07h49m10s +25°49' Gemini -12.0 31'03"1
Mars 07h49m10s +23°39' Gemini 0.5 7"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 98° from the Sun, which is in Pisces 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.
