All five of the planets that are visible to the unaided eye planets will be above the horizon at the same time, shortly after sunset.

It is relatively rare for all of the planets to be aligned in one hemisphere so as to all be above the horizon at the same moment. Such an alignment between the five planets which are visible to the unaided eye happens roughly once every 6 years, while an alignment that also includes Uranus and Neptune, which require binoculars or a telescope to be seen, happens around once every 70 years.

However, since the planets in the outer solar system – especially Saturn, Uranus and Neptune – move quite slowly through the constellations, such alignments can occur multiple times in quick succession, or not at all for over 100 years.

The positions of all the planets at sunset will be as follows:

Planet Altitude
at sunset
Direction

Planet
sets at
Mag Constellation
Mercury 18.0° west 21:42 0.2 Taurus
Venus 22.3° west 22:04 -3.9 Aries
Saturn 25.3° west 22:18 0.0 Taurus
Mars 25.9° west 22:25 1.6 Taurus
Jupiter 48.9° west 00:27 -2.1 Gemini

Celestial coordinates

The positions of each of the planets will be:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 02h56m 16°47'N Aries -3.9 10"7
Jupiter 06h39m 23°19'N Gemini -2.1 35"3
Saturn 04h42m 20°49'N Taurus -0.0 17"0
Mercury 04h07m 23°36'N Taurus 0.2 7"9
Mars 03h57m 21°10'N Taurus 1.6 4"1

The coordinates above are given in J2000.0.

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.
