Sky spectacle on August 12: Perseid meteor shower and six planets align

Skywatchers are preparing for one of the most remarkable dates on the 2026 astronomical calendar. On August 12, the peak of the Perseid meteor shower, a six-planet alignment and a total solar eclipse will all occur on the same day.

However, these celestial events will not be visible at the same time or from every location. Observers in Türkiye will be able to watch the Perseid meteor shower and, under suitable conditions, see some of the planets. The total solar eclipse will not be visible from Türkiye.

The Perseids, widely regarded as one of the most impressive meteor showers of the year, will reach peak activity during the night of August 12 and the early hours of August 13.

The Perseid meteor shower occurs when Earth passes through a trail of debris left behind by Comet 109P/Swift-Tuttle. Tiny particles enter Earth’s atmosphere at high speed, burn up and produce bright streaks of light across the sky.

The 2026 peak will coincide with a New Moon, creating particularly favourable viewing conditions. With almost no moonlight interfering, observers in dark areas away from cities may be able to see a greater number of meteors.

Under ideal weather and viewing conditions, dozens of meteors may be visible every hour. Reports of up to 100 meteors per hour represent a theoretical maximum calculated for exceptionally dark skies, clear weather and an unobstructed viewing location. The actual number visible from cities will be considerably lower because of light pollution.

People wishing to observe the Perseid meteor shower should find a dark and open location away from city lights on the night of August 12. No telescope or binoculars are required. Meteors can appear in different parts of the sky, so watching a wide area with the naked eye generally provides the best experience.

The most favourable viewing period is expected to begin after midnight and continue until dawn on August 13. Observers should avoid looking at mobile phones and other bright screens for about 20 to 30 minutes to allow their eyes to adjust to the darkness.

Before sunrise on August 12, Jupiter, Mercury, Mars, Uranus, Saturn and Neptune will appear spread across a broad section of the sky.

The event is commonly described as a planetary alignment or planet parade. It does not mean that the six planets will form a physically straight line in space. From Earth, they will appear arranged along the ecliptic, the path followed by the Sun and planets across the sky.

Jupiter, Mercury, Mars and Saturn may be visible to the naked eye under suitable conditions. Binoculars or a telescope will be required to observe Uranus and Neptune.

Mercury will be particularly close to the horizon, giving observers only a limited opportunity to see it before the increasing light of dawn. A clear eastern horizon, low light pollution and cloudless weather will improve the chances of observing the display.

A total solar eclipse will also take place on August 12, 2026. The total phase will be visible from Greenland, Iceland, northern Russia, parts of Spain and a small corner of Portugal. A partial solar eclipse will be visible across much of Europe, northwestern Africa and parts of North America.

Türkiye will remain outside the eclipse’s visibility zone. Therefore, neither the total nor the partial phase of the August 12 solar eclipse will be observable from the country. Skywatchers in Türkiye will instead be able to follow live broadcasts expected to be provided by NASA and other scientific institutions.

People watching the eclipse from countries within its visibility zone must never look directly at the Sun without suitable protection. Ordinary sunglasses do not protect the eyes from harmful solar radiation. Observers should use certified eclipse glasses compliant with the ISO 12312-2 safety standard or an approved solar viewer.

Although all three astronomical events fall on the same date, they will not be observed simultaneously. The six-planet display will occur before sunrise on the morning of August 12. The solar eclipse will take place later in the day over its visibility zone, while the Perseid meteor shower will reach its peak during the night of August 12 and the early hours of August 13.

For observers in Türkiye, the Perseid meteor shower will be the main event. If the weather remains clear, locations away from artificial lights could offer one of the most impressive skywatching experiences of the summer.
