Conjunction of the Moon and Jupiter

The Moon and Jupiter will share the same right ascension, with the Moon passing 20' to the north of Jupiter. The Moon will be 25 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 dawn sky, rising at 01:45 (EST) and reaching an altitude of 41° above the southern horizon before fading from view as dawn breaks at around 06:39.

The Moon will be at mag -11.3, and Jupiter at mag -1.9, both in the constellation Virgo.

The pair will be close enough to fit within the field of view of a telescope, but will also 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 12h54m00s 4°07'S Virgo -11.3 31'21"9
Jupiter 12h54m00s 4°28'S Virgo -1.9 32"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 61° 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.
