The Moon and Mars will make a close approach, passing within 1°10' of each other. From some parts of the world, the Moon will pass in front of Mars, creating a lunar occultation. The Moon will be 6 days old.

From Los Angeles , the pair will become visible at around 19:58 (PST), 70° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 01:55.

The Moon will be at mag -11.8; and Mars will be at mag 1.0. Both objects will lie in the constellation Gemini.

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 Mars 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 07h10m40s 25°45'N Gemini -11.8 31'59"6
Mars 07h09m40s 24°36'N Gemini 1.0 6"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 83° from the Sun, which is in Pisces at this time of year.
