The Moon and Saturn will make a close approach, passing within 3°33' of each other. The Moon will be 19 days old.
From Cambridge, the pair will be visible in the morning sky, becoming accessible around 22:13, when they rise to an altitude of 7° above your eastern horizon. They will then reach its highest point in the sky at 03:27, 45° above your southern horizon. They will be lost to dawn twilight around 05:27, 38° above your south-western horizon.
The Moon will be at mag -12.6, and Saturn at mag 0.6, both in the constellation Pisces.
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 Saturn 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 139° from the Sun, which is in Leo 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.
