⁠⁠Patterns in the Sky: All about the Shapes Formed by Earth, Moon and Stars

Have you ever wondered why the sun moves from east to west in the sky each day? This is called a pattern in the sky that we see repeating over and over again at the same interval. There are many such interesting patterns in the sky that we observe every day. They tell us about the position of various celestial objects such as the sun, moon and stars during the day and in the night sky. Let’s explore some common patterns in the sky and their meaning.

What is meant by Patterns in the Sky

Pattern in the sky refers to the things that repeat over and over again in the same way, such as, the movement of sun from east to west in the sky is a pattern we notice each day. Based on the position, shape and size of the celestial bodies we can observe many different patterns of sun, moon and stars in the sky. Observing these different patterns in the sky helps us predict their position and what may happen next.

Sun and Moon Patterns in the Sky

The sun’s apparent movement from east to west in the sky is a pattern that happens due to earth’s rotation on its axis. When the earth spins on its own axis while rotating around the sun, the part of the earth that gets sunlight experiences day while the other half experiences night. By looking at the sun’s position in the sky, we predict the next event. For example, after every night the sun rises from the east. 

Similar to the sun, our moon also follows a particular pattern in movement. We see the moon in the sky every night in different sizes and shapes due to its rotation around the earth. The pattern in which the moon appears in different sizes throughout the month is called the lunar cycle. 

Star Patterns in the Sky

Patterns of stars in the sky are called constellations. Stars appear in some different patterns in the sky, some of them joining together in well predictable shapes such as a spoon. There are around 88 different constellations we can observe in the sky. Their position changes during the year due to earth’s rotation and orbit. Some of the common constellations include ursa major, orion and zodiac constellations. These constellations or star patterns in the sky have been observed and followed since ancient times by explorers and sailors to find the directions and navigate safely in water.

Interesting Facts about Patterns in the Sky

• The famous big dipper constellation that looks like a ladle or spoon shape is an asterism. It is a small part of the Ursa major constellation.
• Ursa major is the Latin word for great bear. In India, it is known as the saptarshi which means seven sages.
• The pattern of the moon in the sky was observed to tell the date in the past using a lunar calendar. It was based on the motion and appearance of the moon in the sky
• The pattern of sun during the day was the basis of our very first clock such as sundial.
