How Many People Will See the September Solar Eclipse 2025?

Unlike a total solar eclipse, which attracts millions of viewers worldwide, a partial solar eclipse has a smaller reach. For the September 2025 eclipse, it is estimated that:

16.6 million people (0.20% of world population) will see any part of the eclipse.

Around 7 million people will see at least 10% of the Sun covered.
Roughly 5 million people will experience 40–50% coverage.
The highest coverage, at 70% partial eclipse, will be visible to only about 409,000 people.

*These numbers highlight how localized this event is compared to more dramatic total eclipses.

Why This September Solar Eclipse 2025 Is Special

Sunrise Eclipse in New Zealand – Observers will see the Sun rise already partially covered by the Moon, creating a rare and dramatic spectacle.

Remote Viewing Locations – The eclipse path primarily crosses remote Pacific regions, giving island nations and research stations in Antarctica a unique experience.
Astronomical Significance – This eclipse is part of Saros cycle 155, a repeating series of eclipses that occur every 18 years, 11 days.

Safety Tips for Watching the Solar Eclipse 2025

Even though it is a partial eclipse, looking directly at the Sun without protection can cause permanent eye damage. To watch safely:

Use certified solar viewing glasses.
Alternatively, use indirect projection methods like a pinhole projector.

Never look at the Sun through sunglasses, cameras, or telescopes without proper solar filters.
