Conjunction of Mars and Uranus

From the Conjunctions feed


Mars and Uranus will share the same right ascension, with Mars passing 1°27' to the south of Uranus.

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 19° above the horizon at dusk.

Mars will be at mag 0.9, and Uranus at mag 5.6, both in the constellation Scorpius.

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 Uranus 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 15h58m10s 21°49'S Scorpius 0.9 5"8
Uranus 15h58m10s 20°21'S Scorpius 5.6 3"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 62° from the Sun, which is in Virgo 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.
