The Moon and Mars will make a close approach, passing within 2°59' of each other.
From Washington (click to change), the pair will be visible in the morning sky. They will become accessible at around 23:21, when they rise 7° above your eastern horizon. They will then reach its highest point in the sky at 04:20, 45° above your southern horizon. They will be lost to dawn twilight at around 07:01, 31° above your south-western horizon.
At the moment of closest approach, the Moon will be at mag -12.4, and Mars at mag -0.6, both in the constellation Virgo.
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.
The precise positions of the Moon and Mars 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 123° from the Sun, which is in Aquarius at this time of year.
The circumstances of this event were computed from the DE405 ephemeris published by the Jet Propulsion Laboratory (JPL).
The positions of deep sky objects in conjunctions are taken from the NGC2000.0 catalogue.
