Which constellation contains the star Sirius?

Which constellation contains the star Sirius?

• A. Orion
• B. Canis Major
• C. Aquila
• D. Pegasus

Answer: (B)

Sirius, known as the Dog Star, is the brightest star in the night sky and is located in the constellation Canis Major. This constellation is associated with a large dog, which is fitting since the name "Canis Major" translates to "Greater Dog" in Latin. Sirius is often depicted as the dog that follows Orion, the Hunter, which is a separate constellation nearby in the sky. The prominence of Sirius in Canis Major has made it a significant marker for navigation and seasonal changes throughout history.

In contrast, the other constellations mentioned do not contain Sirius. Orion, while it is a prominent constellation that features Betelgeuse and Rigel, does not house Sirius itself. Aquila, the Eagle, and Pegasus, which is known for its square-shaped asterism, also do not include Sirius. Therefore, Canis Major is the correct answer because it directly contains the star Sirius.
