What is a supermoon?
A supermoon occurs when a full moon coincides with the moon's closest approach to Earth, called perigee. This makes the moon appear larger and brighter than usual, often up to 14% bigger and 30% brighter. The phenomenon is purely based on the moon's orbit and its distance from Earth.

Why is October's supermoon called the Harvest Moon?
October's supermoon is also known as the Harvest Moon because it is the full moon nearest to the autumn equinox. Historically, it provided extra light for farmers harvesting crops at night, making it culturally significant and visually stunning.

When are the next supermoons happening this year?
After October's supermoon, there will be two more in 2025—one in November, called the Beaver Moon, and another in December, known as the Cold Moon. This sequence of three consecutive supermoons is quite rare and offers multiple opportunities for skywatchers to observe these bright, large moons.

How does a supermoon affect tides and nature?
Supermoons can cause higher-than-normal tides, known as perigean spring tides. These can lead to more dramatic coastal flooding and influence marine life. The increased gravitational pull also affects animal behaviors and can enhance the beauty of the night sky for observers.
-
Can I see the supermoon with my naked eye?
Yes, supermoons are visible to the naked eye and do not require any special equipment. To get the best view, find a dark spot away from city lights, and consider using binoculars for a closer look at the moon's surface details.

What makes this supermoon different from others?
This year's October supermoon is notable because it is part of a rare sequence of three consecutive supermoons, making it more spectacular and scientifically interesting. Its brightness and size are enhanced by its proximity to Earth, providing a stunning view for skywatchers worldwide.
