Which is the smallest star in Orion?

Answer 1

The smallest star in the Orion constellation is likely Beteigeuze (Alpha Orionis), which is a red supergiant. However, in terms of size and mass, the least massive stars in Orion, such as the faint red dwarfs, would qualify as the smallest. Among the prominent stars, Bellatrix (Gamma Orionis) is often considered smaller than the more massive stars in the constellation. Nonetheless, specific measurements and classifications can vary based on criteria like size, mass, and luminosity.
