The Moon and Jupiter will make a close approach, passing within 5°40' of each other. The Moon will be 3 days old.

From South El Monte , the pair will become visible at around 19:36 (PDT), 39° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 35 minutes after the Sun at 22:55.

The Moon will be at mag -10.7; and Jupiter will be at mag -2.1. Both objects will lie in the constellation Taurus.

They will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

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 04h09m00s 26°13'N Taurus -10.7 32'23"7
Jupiter 04h13m30s 20°39'N Taurus -2.1 33"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 45° from the Sun, which is in Pisces 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.
