The Moon and Mars will share the same right ascension, with the Moon passing 32' to the north of Mars. The Moon will be 15 days old.

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

From Seattle , the pair will be visible between 16:56 and 07:07. They will become accessible at around 16:56, when they rise to an altitude of 7° above your north-eastern horizon. They will reach their highest point in the sky at 00:02, 67° above your southern horizon. They will become inaccessible at around 07:07 when they sink below 7° above your north-western horizon.

The Moon will be at mag -12.6, and Mars at mag -1.9, both in the constellation Taurus.

The pair will be a little too widely separated to fit comfortably 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 04h57m10s 25°30'N Taurus -12.6 29'50"3
Mars 04h57m10s 24°57'N Taurus -1.9 17"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 177° from the Sun, which is in Ophiuchus 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.
