Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 4°09' to the south of Mars. The Moon will be 29 days old.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 0° above the horizon at dawn.

The Moon will be at mag -8.5, and Mars at mag 1.4, both in the constellation Sagittarius.

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 18h17m10s 28°10'S Sagittarius -8.5 32'19"3
Mars 18h17m10s 24°01'S Sagittarius 1.4 3"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 16° from the Sun, which is in Sagittarius at this time of year.

Warning

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.

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.
