The Moon and Jupiter will share the same right ascension, with the Moon passing 0°54' to the south of Jupiter. The Moon will be 8 days old.

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

From Cambridge, the pair will be visible in the evening sky, becoming accessible around 17:37 (EDT) as the dusk sky fades, 67° above your southern horizon. They will then reach their highest point in the sky at 18:09, 68° above your southern horizon. They will continue to be observable until around 00:47, when they sink below 7° above your western horizon.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -11.9, and Jupiter at mag -2.4, 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 04h19m50s +20°01' Taurus -11.9 29'33"4
Jupiter 04h19m50s +20°55' Taurus -2.4 39"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 96° from the Sun, which is in Aquarius 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.
