The Moon and Mars will make a close approach, passing within a mere 5.0 arcminutes 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 2 days old.

From Jacksonville however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 10° above the horizon at dusk.

The Moon will be at mag -9.5; and Mars will be at mag 1.8. Both objects will lie in the constellation Cancer.

They will be close enough to fit within the field of view of a telescope, but will also 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 08h59m00s 18°27'N Cancer -9.5 30'42"1
Mars 08h59m00s 18°23'N Cancer 1.8 3"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 28° from the Sun, which is in Gemini at this time of year.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
