In early June, six planets – Jupiter, Mercury, Uranus, Mars, Neptune and Saturn – will line up in the morning sky in the Northern Hemisphere. This is known as a planetary conjunction.
The alignment will be visible before sunrise on June 3rd from New York City. However, viewing all six planets together may be difficult due to several factors:
Tall buildings or mountains could block the view.
The rising sun will light up the sky, making the more distant Neptune and Uranus hard to see.
Visiting an observatory or astronomy event may improve chances of spotting some planets, but seeing all six at once is unlikely.
Other planetary sightings are possible in June, like Mars, Jupiter and Saturn visible together before sunrise on June 21st. Another conjunction of the Moon, Mars, Jupiter and Saturn is predicted on June 29th.
To maximize viewing chances, observers are advised to find a dark site away from light pollution and obstacles, and use telescopes or binoculars to spot the smaller or more distant planets.
