Supermoons: What They Are & When To See Them

A supermoon is a captivating astronomical event that occurs when a full moon or a new moon coincides with the closest point in its orbit to Earth. Simply put, it's when the moon appears noticeably larger and brighter than usual. This celestial alignment offers a striking visual treat for skywatchers and has sparked intrigue for centuries. In this guide, we'll dive deep into what constitutes a supermoon, explore how it happens, and provide you with tips on how to witness this spectacular event.

What Causes a Supermoon?

The term "supermoon" isn't a technical astronomical term. It’s a popular term to describe a perigean full moon (or new moon). Let's break down the science:

The Moon's Orbit

The moon doesn't orbit Earth in a perfect circle. Its path is elliptical (oval-shaped). This means the distance between the moon and Earth varies throughout its orbit. — Hertz Phone Numbers: Get Instant Support

Perigee and Apogee

• Perigee: This is the point in the moon's orbit when it's closest to Earth. When a full or new moon occurs near perigee, we get a supermoon.
• Apogee: This is the point in the moon's orbit when it's farthest from Earth. A full moon at apogee is sometimes called a micromoon; it appears smaller than a supermoon.

The Supermoon Effect

When a full moon aligns with perigee, it appears up to 14% larger and 30% brighter than a full moon at its apogee. This is what makes a supermoon such a visually stunning event. The difference in size is more noticeable to the naked eye than the change in brightness. — Moving To Europe: What Americans Should Know Before Relocating

How Often Do Supermoons Happen?

Supermoons aren't rare; they occur several times a year. However, the exact number varies depending on the lunar cycle and the alignment of the Earth, moon, and sun. Typically, there are 3-4 supermoons in a given year, sometimes more. Because the orbit of the moon is elliptical, the distance from the earth changes and therefore the visibility of the supermoon.

Supermoon Frequency

Full moons occur roughly every 29.5 days. Because the moon's orbit is not a perfect circle, the distance to the earth varies. The perigee, or the closest point in the orbit to Earth, is a bit closer than a perfect circle. A supermoon is when a full moon occurs when the moon is at or near its perigee.

Factors Influencing Supermoon Visibility

• Weather conditions: Clear skies are essential for optimal viewing.
• Light pollution: Observing from areas with minimal light pollution enhances the experience.
• Timing: Supermoons are best viewed when they are rising or setting.

Tips for Viewing a Supermoon

Want to experience the wonder of a supermoon? Here are some helpful tips:

Find the Right Location

• Dark Skies: Get away from city lights. The darker the location, the better your view.
• Open Horizon: Find a spot with a clear view of the horizon, such as a field, beach, or hilltop. This helps with the moon illusion, making the moon appear even larger.

Best Time to Watch

• Moonrise/Moonset: The best time to view a supermoon is during moonrise (when it's rising above the horizon) or moonset (when it's setting). This is when the moon illusion is most pronounced.

What to Bring

• Comfort: Bring a blanket or chair for comfortable viewing.
• Binoculars or Telescope: While not necessary, binoculars or a telescope can enhance your viewing experience.
• Patience: Allow your eyes to adjust to the darkness.

The Cultural and Historical Significance of Supermoons

Supermoons have fascinated people for centuries and have found their way into various cultures and beliefs.

Ancient Beliefs and Folklore

Across different cultures, supermoons have often been associated with:

• Spiritual Significance: Many cultures believe that supermoons amplify energies and emotions.
• Harvest and Cycles: Supermoons sometimes coincide with key seasonal events, such as harvest times.

Supermoons in Modern Culture

Supermoons continue to capture the public's imagination, influencing:

• Art and Literature: Supermoons frequently appear as a subject in art and literature, representing mystique and beauty.
• Scientific Interest: Supermoons are a subject of ongoing study by scientists. They study its effects on the earth, such as the tides.

Supermoon vs. Other Moon Phases

It's useful to understand how a supermoon compares to other moon phases.

Full Moon vs. Supermoon

• Full Moon: The moon appears fully illuminated from Earth.
• Supermoon: A full moon that occurs near the perigee. It is bigger and brighter than a typical full moon.

New Moon vs. Supermoon

• New Moon: The moon is not visible from Earth.
• Supermoon (New Moon): When a new moon aligns with perigee, it can cause higher-than-usual tides, and affect how much sunlight is reflected.

Micromoon

A micromoon is a full moon that occurs near its apogee (farthest point from Earth) and will appear smaller and less bright than normal.

Where Can I Find Supermoon Dates?

Several websites and apps provide accurate supermoon dates. Some reliable resources include:

FAQs About Supermoons

1. What exactly is a supermoon? A supermoon is a full moon (or new moon) that occurs when the moon is at or near its closest point to Earth (perigee), making it appear larger and brighter than usual.

2. How does a supermoon differ from a regular full moon? A supermoon appears up to 14% larger and 30% brighter than a regular full moon. This is because it is closer to Earth in its orbit.

3. Are supermoons rare? No, supermoons are not rare. They occur several times a year, depending on the lunar cycle and the moon's orbit.

4. Where is the best place to view a supermoon? The best place to view a supermoon is in a location with dark skies, away from light pollution, and with a clear view of the horizon.

5. What time is the best time to see a supermoon? The best time to view a supermoon is during moonrise or moonset, when it appears closest to the horizon and the moon illusion is most pronounced.

6. Do supermoons affect tides? Yes, supermoons can cause higher-than-usual tides, known as spring tides. This is because the moon's gravitational pull is stronger when it's closer to Earth. The earth's tides are affected by the moon. This is because of the gravitational pull of the moon, which is strongest when the moon is closest to the earth. Supermoons make the pull even stronger, resulting in higher tides. — Clinton, Iowa Zip Code: Find It Here!

7. What is the moon illusion? The moon illusion is an optical effect that makes the moon appear larger when it is near the horizon. It has nothing to do with the actual distance of the moon from the earth but is a trick of the eye. When the moon is close to the horizon, it is being viewed through a lot more of the atmosphere. This atmospheric distortion is why the moon appears bigger when it is closer to the horizon.
