Answer: (D) constellation
Answer: (D) constellation
Answer: (D) constellation
Substitute Word: constellation.
Synonyms: Asterism.
A constellation is a recognized grouping of stars that forms a distinct pattern in the night sky. These patterns have been given names and stories throughout history, often associated with mythology or folklore. Examples include Orion, Ursa Major (the Big Dipper), and Taurus.
An asterism is a smaller, less formally defined group of stars within a constellation or sometimes across multiple constellations. They often form recognizable patterns but aren't officially recognized as constellations. Examples include the Big Dipper (part of Ursa Major) and the Summer Triangle (formed by stars from three different constellations).
So, whether a group of stars is called a constellation or an asterism depends on its size, shape, and whether it has been officially recognized by astronomical societies.
