And, the answer for the the question is :
Explanation:
A pattern of stars is known as an asterism. Although “constellation” is the term that is most commonly used to describe a pattern of stars, there is in fact a difference between “constellation” and “pattern.” While a constellation is technically a formally-defined region of the sky in which celestial objects (stars, galaxies, etc.) represent a person, creature, or item from mythology, an asterism is simply a group of stars that form a visual pattern. (Many constellations are made up of many asterisms, which further adds to the already existing confusion.) This discrepancy often leads to misunderstandings, which is why in 1925 the International Astronomical Union took action to legally name 88 official constellations. Although many people are under the impression that it is a constellation, the Big Dipper is actually an example of an asterism. Today, it is likely the most well-known example of an asterism.
An asterism is a pattern of stars that is smaller than a constellation, but still recognizable and significant in its own right. Unlike constellations, which are defined by official boundaries and recognized by astronomers and scientists, asterisms are often informal and subjective, and may vary depending on the observer’s location and perspective.
Some of the most famous and recognizable asterisms include the Big Dipper, the Little Dipper, and Orion’s Belt. These patterns of stars have been recognized and named by cultures around the world for thousands of years, and have played a significant role in mythology, astronomy, and navigation.
The Big Dipper, for example, is a pattern of seven stars that is part of the constellation Ursa Major. It is easily recognizable and has been used for centuries as a navigational tool, particularly by sailors and travelers who relied on the stars to guide their journeys.
Similarly, Orion’s Belt is a pattern of three stars that is part of the constellation Orion. It is often used as a reference point for astronomers and stargazers, and is a popular target for telescope observations and astrophotography.
asterisms continue to be an important and beloved part of star lore and culture. They serve as a reminder of the beauty and wonder of the night sky, and the important role that stars have played in human history and exploration. Whether viewed through a telescope or simply appreciated with the naked eye, asterisms are a testament to the enduring power and fascination of the cosmos.
