The Moon and Jupiter will make a close approach, passing within 3°15' of each other. The Moon will be 22 days old.

From Cambridge , the pair will be visible in the morning sky, becoming accessible around 01:06, when they reach an altitude of 7° above your south-eastern horizon. They will then reach their highest point in the sky at 05:05, 29° above your southern horizon. They will be lost to dawn twilight around 06:08, 27° above your southern horizon.

The Moon will be at mag -12.2; and Jupiter will be at mag -2.1. Both objects will lie in the constellation Libra.

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 15h36m40s 21°34'S Libra -12.2 32'17"6
Jupiter 15h38m50s 18°21'S Libra -2.1 37"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 98° 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.
