Morphology
beta + Centauri
The parts are partly compositional: 'beta' signals 'second' (Greek-letter ranking) and 'Centauri' refers to the constellation Centaurus, so the phrase literally points to the 'second (star) of Centaurus'. However, understanding this requires specific knowledge of astronomical naming conventions and the Latin/genitive form used in star names—information that a typical B1 learner who merely knows the surface words would not automatically possess.
Etymology
Beta Centauri comes from an old way of naming stars: Beta means 'second' and Centauri shows it is part of the picture in the sky called Centaurus, a centaur. Imagine a centaur pointing to his 'second brightest' star, so the name tells you it is the 'second brightest' star in Centaurus.
