The Moon and Mercury will share the same right ascension, with the Moon passing 6°40' to the north of Mercury. The Moon will be 1 days old.
The Moon will be at mag -9.0, and Mercury at mag 0.2, both in the constellation Libra.
The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
A graph of the angular separation between the Moon and Mercury 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 coordinates above are given in J2000.0. The pair will be at an angular separation of 20° from the Sun, which is in Virgo at this time of year.
