What major constellation contains the star Eta Carinae?

Eta Carinae is located in the constellation Carina, which is a prominent part of the southern sky. It is known for being one of the most massive and luminous stars in the Milky Way and is situated near the center of the Carina constellation.

Carina is not just a random constellation; it has historical significance and is known for its rich stellar populations and notable celestial objects. Eta Carinae is particularly famous for its drastic variability and wonderful nebula surrounding it, making it a subject of study among astronomers interested in massive stars.

The other constellations mentioned, such as Orion, Aquila, and Scorpius, although they contain interesting stars and objects, do not include Eta Carinae. Orion is well known for its distinct belt and bright stars, Aquila represents the eagle and contains the bright star Altair, while Scorpius is recognized for its scorpion shape and bright stars like Antares. However, none of these constellations is home to Eta Carinae.
