The Moon and Mars will share the same right ascension, with the Moon passing 5°29' to the south of Mars. The Moon will be 2 days old.

From Ashburn (click to change), the pair will become visible at around 19:46 (EST) as the dusk sky fades, 29° above your western horizon. They will then sink towards the horizon, setting 2 hours and 54 minutes after the Sun at 22:22.

The Moon will be at mag -10.1, and Mars at mag 1.5, both in the constellation Aries.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

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 02h47m20s +11°02' Aries -10.1 32'49"4
Mars 02h47m20s +16°31' Aries 1.5 4"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 33° 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.
