A parade of 7 planets in the morning sky

All seven planets will be above the horizon at the same time, shortly before sunrise.

The planets Neptune and Uranus are too faint to be seen with the unaided eye, and a pair of binoculars or a small telescope is needed to see them. Additionally, since they are no brighter than many stars, a finder-chart is needed to show their positions relative to the surrounding stars. Neptune will lie in the constellation of Virgo shining at magnitude 8.0; you can find a chart of its position here. Uranus will lie in the constellation of Gemini shining at magnitude 5.6; you can find a chart of its position here.

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 sunrise will be as follows:

Jupiter 40.9° south-west 22:57 -2.0 Virgo

Saturn 12.0° west 17:43 -0.3 Cancer

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.
