The Moon and Jupiter will make a close approach, passing within 1°30' of each other. The Moon will be 24 days old.
From Cambridge, the pair will be difficult to observe as they will appear no higher than 19° above the horizon. They will be visible in the dawn sky, rising at 03:55 (EDT) – 2 hours and 55 minutes before the Sun – and reaching an altitude of 19° above the south-eastern horizon before fading from view as dawn breaks around 06:31.
The Moon will be at mag -11.3, and Jupiter at mag -2.1, both in the constellation Sagittarius.
The pair 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.
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 closest approach will be as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 65° from the Sun, which is in Pisces at this time of year.

The circumstances of this event were computed using the DE405 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.
