Mercury and Uranus will share the same right ascension, with Mercury passing 2°54' to the south of Uranus.

From San Diego however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 0° above the horizon at dawn.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

Mercury will be at mag 0.0, and Uranus at mag 5.9, both in the constellation Aries.

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 Mercury 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
Mercury 03h10m40s 14°33'N Aries 0.0 7"2
Uranus 03h10m40s 17°27'N Aries 5.9 3"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 23° from the Sun, which is in Taurus 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.
