A rare celestial event graced our skies in 2025 when seven planets – Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune – aligned in what astronomers call a “planetary parade.” This spectacular alignment won’t occur again until 2040, giving stargazers a limited window to witness this uncommon astronomical phenomenon.
The planetary parade occurs when the planets appear to form a line across the night sky from Earth’s perspective. While the planets remain separated by vast distances in space, they are visible simultaneously for observers on Earth.
“There’s a rare opportunity to have seven planets in essentially a convenient place for you to look for them,” said Dr. Edward Bloomer, an astronomer at the Royal Observatory Greenwich.
When and How to View
The best time to view the alignment was just after sunset. Different locations experienced optimal viewing on different dates – Tokyo began seeing the parade on February 22, while New York had the best view on February 25, according to the Star Walk sky-gazing app.
Worldwide, February 28 offered the most favorable conditions for viewing. However, the window to see all seven planets was brief, particularly for Saturn and Mercury, which quickly dropped below the horizon after sunset.
“You really only have a few minutes after sunset to catch them before they drop below the horizon. After that, you’ll still be able to see Venus, Jupiter, and Mars clearly for a much longer time,” Dr. Bloomer explained.
Four planets – Mercury, Venus, Mars, and Jupiter – were visible to the naked eye, with Venus appearing as the brightest. Saturn was more difficult to spot due to its position low on the horizon. Uranus and Neptune required binoculars or a telescope.
Mars appeared reddish and high in the sky near the Gemini constellation, while Jupiter was lower, near Taurus. Venus was highly visible near Pisces. Mercury was near the western horizon in Aquarius, and Saturn was also low on the horizon.
Viewing Tips
For the best view, astronomers recommended finding a location with minimal light pollution and a clear view of the western horizon. Clear skies were essential to see all planets.
“If you just pop out of your kitchen into your back garden, you will take time to adjust to the light levels. Give it a bit of time – your eyes take about half an hour to fully adjust,” advised Dr. Bloomer.
He also suggested: “Avoid looking at your phone, get comfortable, and ensure you have an unobstructed view of the horizon.”
While Venus and Jupiter were easy to spot due to their brightness, seeing all seven planets required planning and patience. Binoculars or telescopes were recommended for a clearer view, especially for Uranus and Neptune.
Scientific Perspective
From a scientific standpoint, planetary alignments occur because the planets orbit the Sun within roughly the same flat plane as Earth. As Gerard van Belle, director of science at Lowell Observatory in Arizona, explained, the configuration is similar to a vinyl record, with the Sun at the center and the planets moving along different “grooves” or orbits.
Our view from Earth is along one of those grooves, which is why planets always appear roughly along the same line in the sky, known as the ecliptic – the same path the Sun follows during the day.
While such alignments may appear mystical, astronomers note they are natural astronomical events that occur periodically. “On the scale of supermoon to death asteroid, this is more a supermoon sort of thing,” said Dr. van Belle, adding that it “makes for a very nice excuse to go outside at night, maybe with a glass of wine, and enjoy the night sky.”
Science communicator Jenifer Millard emphasized the value of witnessing such events firsthand, describing it as a humbling experience that connects observers to the broader cosmos.
Future Alignments
After the 2025 alignment, we’ll have to wait until 2040 for the next seven-planet parade. However, smaller alignments will occur more frequently. In late August 2025, four planets will be visible before sunrise, and in late October 2028, five planets will align before sunrise. Another five-planet alignment will occur in late February 2034, visible after sunset.
“In summary, while they aren’t once-in-a-lifetime events, planetary parades afford an uncommon opportunity to look up and appreciate our place in our solar system, with diverse worlds arrayed across the sky before our very eyes,” NASA states on its website.

The 2025 planetary parade coincided with India’s Maha Kumbh Mela, adding cultural significance to this astronomical event in some parts of the world.
Dr. Bloomer encourages people to make a habit of stargazing beyond this special event. “See how things change,” he said, adding that observing the heavens is “a chance to witness the ongoing mechanics of the solar system at work.”
FAQ
When exactly was the planetary parade visible in 2025?
The planetary parade was visible at different times depending on location. Tokyo began seeing it on February 22, while New York had optimal viewing on February 25. Worldwide, February 28 offered the best conditions for viewing. The alignment was visible just after sunset.
Can I see all seven planets with the naked eye?
No, not all planets were visible without equipment. Mercury, Venus, Mars, and Jupiter could be seen with the naked eye. Saturn was visible but harder to spot as it was low on the horizon. Uranus and Neptune required binoculars or a telescope to observe.
How long did the planetary alignment last?
The window to see all seven planets was very brief, particularly for Mercury and Saturn, which quickly set below the horizon after sunset. Other planets like Venus, Jupiter, and Mars remained visible for a longer time in the night sky.
What’s the best way to view planetary parades?
For optimal viewing, find a location with minimal light pollution and a clear view of the western horizon. Give your eyes about 30 minutes to adjust to the darkness, avoid looking at your phone screen, and use binoculars or a telescope if available. Clear skies are essential for the best experience.
Why are planetary alignments considered rare?
Planetary alignments occur when planets appear in a line from Earth’s perspective. While smaller alignments of 4-5 planets happen every few years, a seven-planet alignment is uncommon. The next time all seven planets will align like this won’t be until 2040, making the 2025 event relatively rare.
Do planetary alignments have any scientific significance?
Scientifically, planetary alignments demonstrate the mechanics of our solar system. They occur because all planets orbit the Sun on roughly the same plane. While they don’t have major scientific impacts, they provide valuable opportunities for public engagement with astronomy and for observers to appreciate the structure of our solar system.
