Six planets, Mercury, Venus, Jupiter, Saturn, Uranus and Neptune, will appear together in the night sky starting on August 17. This rare "planetary parade," sometimes mistaken for a planetary alignment, will continue until August 20. Photo: Peter Zay/Anadolu via Getty Images via Getty Images.

The celestial conjunction, last seen in February 2025, will appear in the eastern sky about an hour before sunrise. While most of the planets have been visible in the morning sky for weeks, Mercury will join the show this time, bringing the total number of planets from five to six. Image: skyatnightmagazine.

Under clear skies, stargazers will be able to observe Venus, Jupiter and Saturn. Mercury will be closer to the horizon but still bright enough for most observers to see. Photo: Rui Santos, Pinhal de Leiria, Portugal, February 28, 2025.

However, Uranus (located between Jupiter and Saturn) and Neptune (close to Saturn) are too dim and too far away to be seen with the naked eye. The only way to see these two planets is with a good telescope. Photo: Stellarium.

It's rare to see six planets in the sky at the same time, and the beauty of the phenomenon is enhanced by the crescent moon. Photo: skyatnightmagazine.

Mercury can be seen below Jupiter and Venus, but will be easier to see on August 19. On the morning of August 19 and August 20, a thin crescent moon will be very close to Jupiter and Venus - a visual highlight of the "planetary parade". Photo: Angela Hegarty.
