📖 What is it?

Did you know that if you took a photograph of the Sun from the same place at the same time every day for an entire year, the Sun wouldn't stay in the same position?

Instead, it would slowly trace a giant figure eight in the sky!

This incredible shape is called an analemma.

(Use the photos you captured from the video here.)

🌍 Where would you use it?

Understanding the analemma can help you learn about:

🌍 How the Earth moves around the Sun.
🧭 Navigation and finding direction.
📷 Time-lapse photography.
🔭 Astronomy.
🗺️ Why sunrise and sunset change throughout the year.

🤔 Why is it important?

The analemma helps scientists and astronomers understand how our planet moves through space.

It also explains why:

The Sun is higher in summer.
The Sun is lower in winter.
Daylight hours change throughout the year.
The exact time of solar noon isn't always the same.

⚙️ How does it work?

The figure-eight shape happens because of two important reasons:

🌍 1. The Earth is tilted

The Earth leans on its axis by about 23.5°.

This tilt changes how high the Sun appears in the sky throughout the year.

☀️ 2. Earth's orbit isn't a perfect circle

Our planet travels around the Sun in a slightly oval-shaped path.

Sometimes Earth moves a little faster.

Sometimes it moves a little slower.

This changes where the Sun appears each day, helping create the sideways part of the figure eight.

Together, these two effects create the amazing analemma.

🧰 What equipment do you need?

If you'd like to make your own analemma, you'll need:

📷 A camera.
📍 The exact same location.
⏰ A reminder to take one photo at the same time every sunny day.
📅 Patience! (It takes around a year.)

🪜 Step-by-step Guide

Step 1

Choose one location where you can clearly see the Sun.

Step 2

Take one photograph at exactly the same time.

Step 3

Return every sunny day and repeat.

Step 4

After many months, combine the photographs.

Step 5

Watch as the Sun forms a giant figure eight in the sky!

⚠️ Safety First

⚠️ Never look directly at the Sun with your eyes, binoculars or a telescope.

Doing so can permanently damage your eyesight.

If you want to photograph the Sun, ask a trusted adult to help and use suitable equipment.

🌟 Amazing Fact

The word analemma comes from an ancient Greek word meaning "support" or "pedestal."

Every planet with a tilted axis and an orbit around the Sun can have its own version of an analemma—but each one looks different!

🧠 Explorer Challenge

🌞 Over the next month:

Watch where the Sun rises.
Notice where it sets.
Is it in exactly the same place every day?

Write down your observations and see if you can spot the gradual changes!
