Alpha Orionis is also referred to as?

Alpha Orionis is commonly known as Betelgeuse, which is a red supergiant star located in the constellation of Orion. This star is notable for its brightness and distinctive reddish hue, making it one of the most recognized stars in the night sky. Betelgeuse is one of the largest known stars, with a diameter that far exceeds that of our Sun.

The designation "Alpha Orionis" indicates that it is the brightest star in the constellation Orion, which has been a focal point for astronomers and stargazers alike due to its prominence. Its name, Betelgeuse, is derived from the Arabic phrase that means "the armpit of the central one," referring to its position in the Orion constellation.

In contrast, Cygni Zeta refers to another star in the constellation Cygnus, while Pulsar 47 and Nova Centauri pertain to different celestial phenomena entirely. Pulsar 47 indicates a type of neutron star, and Nova Centauri refers to a specific nova event in the constellation Centaurus. Thus, Betelgeuse stands out both in name and function as a key stellar archetype in Orion.
