Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 45' to the south of Jupiter. The Moon will be 14 days old.

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

From Columbus , the pair will be visible in the evening sky, becoming accessible around 17:27 (EDT), 15° above your eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 23:04, 67° above your southern horizon. They will continue to be observable until around 05:22, when they sink below 7° above your western horizon.

The Moon will be at mag -12.5, and Jupiter at mag -2.8, 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 Jupiter 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 03h28m40s 17°01'N Taurus -12.5 29'27"9
Jupiter 03h28m40s 17°46'N Taurus -2.8 47"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 160° 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.
