What constellation contains the star Deneb?

• A. Orion
• B. Cygnus
• C. Leo
• D. Sagittarius

Answer: (B)

The star Deneb is located in the constellation Cygnus, which is also known as the Swan. Deneb is one of the brightest stars in the night sky and serves as a key point in the asterism known as the Northern Cross. It is classified as a blue supergiant star, and its name is derived from an Arabic word meaning "tail," as it represents the tail of the swan in the constellation's depiction.

Cygnus is particularly prominent during the summer months in the Northern Hemisphere and is well-known among both amateur and professional astronomers. It is part of the Milky Way and can be easily identified due to the shape formed by its pattern of stars. Its position and brightness make it a critical reference point for navigation in the night sky.

In contrast, the other constellations mentioned—Orion, Leo, and Sagittarius—do not contain Deneb, as they are distinct formations with their own notable stars and characteristics.
