Conjunction of Mars and Neptune

From the Conjunctions feed


Mars and Neptune will share the same right ascension, with Mars passing 1°14' to the south of Neptune.

From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 20° above the horizon at dawn.

Mars will be at mag 0.8, and Neptune at mag 7.9, both in the constellation Capricornus.

The pair will be too widely separated to fit within the field of view of a telescope, but will be visible through a pair of binoculars.

A graph of the angular separation between Mars and Neptune 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
Mars 21h18m30s 17°02'S Capricornus 0.8 6"1
Neptune 21h18m30s 15°47'S Capricornus 7.9 2"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 66° from the Sun, which is in Pisces 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.
