English thesaurus is mainly derived from The Integral Dictionary (TID). The only historical brightest star that came even close to reaching that magnitude is Adhara’s neighbour Mirzam (β CMa), which had an apparent magnitude of -3.65 about 4 million years ago. It had a visual magnitude of -3.99, outshining Jupiter (mag.

[4] With a surface temperature of 21,900 kelvin, the star appears blue-white and is extremely luminous; it emits roughly 20,000 times more energy per second than the Sun.
