Conjunction of Mars and Neptune

Mars and Neptune will share the same right ascension, with Mars passing 2°47' to the north of Neptune.

From South El Monte , the pair will become visible at around 20:21 (PDT), 54° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 00:57.

Mars will be at mag 1.2, and Neptune at mag 7.9, both in the constellation Gemini.

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 06h31m50s 25°04'N Gemini 1.2 5"7
Neptune 06h31m50s 22°17'N Gemini 7.9 2"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 72° from the Sun, which is in Pisces at this time of year.
