The Moon and Jupiter will make a close approach, passing within 3°44' of each other. The Moon will be 14 days old.

From Seattle, the pair will be visible between 20:59 and 05:09. They will become accessible around 20:59, when they rise to an altitude of 7° above your south-eastern horizon. They will reach their highest point in the sky at 01:04, 28° above your southern horizon. They will become inaccessible around 05:09 when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.7 in Aquarius; and Jupiter will be at mag -2.9 in Capricornus.

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 Jupiter 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 22h02m10s -17°17' Aquarius -12.7 31'33"4
Jupiter 21h57m00s -13°45' Capricornus -2.9 48"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 174° from the Sun, which is in Leo 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.
