The Moon and Jupiter will make a close approach, passing within 1°39' of each other. The Moon will be 18 days old.

From Seattle, the pair will be visible in the morning sky, becoming accessible around 22:42, when they rise to an altitude of 7° above your eastern horizon. They will then reach its highest point in the sky at 04:06, 44° above your southern horizon. They will be lost to dawn twilight around 05:42, 39° above your south-western horizon.

The Moon will be at mag -12.5; and Jupiter will be at mag -2.8. Both objects will lie in the constellation Cetus.

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 00h34m20s +00°16' Cetus -12.5 31'41"2
Jupiter 00h31m20s +01°44' Cetus -2.8 45"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 134° from the Sun, which is in Leo 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.
