The Moon and Mars will make a close approach, passing within 1°44' of each other. The Moon will be 27 days old.

From Columbus however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 11° above the horizon at dawn.

The Moon will be at mag -9.7; and Mars will be at mag 1.4. Both objects will lie in the constellation Taurus.

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 04h12m50s 22°48'N Taurus -9.7 30'24"0
Mars 04h13m30s 21°04'N Taurus 1.4 4"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 31° 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.
