Close approach of the Moon and Jupiter

The Moon and Jupiter will make a close approach, passing within 0°43' of each other. The Moon will be 2 days old.

From London however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 6° above the horizon at dusk.

The Moon will be at mag -9.2, and Jupiter at mag -1.8, both in the constellation Sagittarius.

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.

At around the same time, the two objects 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 two objects at the moment of closest approach will be as follows:

The coordinates above are given in J2000.0. The pair will be at an angular separation of 23° from the Sun, which is in Scorpius at this time of year.
