Conjunction of the Moon and Mars

The Moon and Mars will share the same right ascension, with the Moon passing 6°27' to the south of Mars. The Moon will be 18 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Jacksonville , the pair will be visible in the morning sky, becoming accessible around 21:12, when they reach an altitude of 8° above your eastern horizon. They will then reach their highest point in the sky at 03:00, 71° above your southern horizon. They will be lost to dawn twilight around 07:00, 31° above your western horizon.

The Moon will be at mag -12.7 in the constellation Sextans, and Mars at mag -0.7 in the neighbouring constellation of Leo.

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 Mars 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 Moon 10h47m20s 5°39'N Sextans -12.7 32'32"9
Mars 10h47m20s 12°07'N Leo -0.7 12"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 143° from the Sun, which is in Capricornus at this time of year.
