If you're curious about the upcoming celestial events, you're probably wondering when the next supermoon will appear. Supermoons happen when the full moon coincides with its closest approach to Earth, making it look larger and brighter in the night sky. In October 2025, skywatchers will experience a spectacular supermoon, along with other astronomical phenomena like comets and meteor showers. Below, you'll find answers to common questions about supermoons, their effects, and what makes this month's sky so special.
-
When is the next supermoon happening?
The next supermoon is scheduled for October 7, 2025. It will be the first of three supermoons this season, featuring the Harvest Moon, which appears up to 14% larger and 30% brighter than a typical full moon.
-
How does a supermoon affect ocean tides?
Supermoons have a noticeable impact on ocean tides because the moon's gravitational pull is stronger when it is closer to Earth. This results in higher high tides and lower low tides, known as 'spring tides,' which can cause more dramatic coastal changes.
-
Why does the moon look so big during a supermoon?
The moon appears larger during a supermoon because it is at its closest point to Earth, called perigee. This proximity makes the moon seem up to 14% bigger and brighter than usual, creating a striking visual effect in the night sky.
-
What is the significance of the Harvest Moon?
The Harvest Moon is the full moon that occurs closest to the autumnal equinox, usually in September or October. It has cultural significance as it traditionally helped farmers harvest crops late into the night before modern lighting, and it often appears larger and more luminous near the horizon.
-
Will there be more supermoons this year?
Yes, after the October supermoon, there will be additional supermoons in November and December 2025. These events continue to offer spectacular viewing opportunities for sky enthusiasts.
-
What other celestial events are happening in October 2025?
In October 2025, besides the supermoon, skywatchers can enjoy the visibility of comet C/2025 A6 Lemmon, which reaches peak brightness late in the month, and the Orionid meteor shower on October 20, which is linked to debris from Halley's Comet.
