Difference between Apparent magnitude and Aquarius (constellation)

Apparent magnitude vs. Aquarius (constellation)

The apparent magnitude of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth. Aquarius is a constellation of the zodiac, situated between Capricornus and Pisces.

Almagest

The Almagest is a 2nd-century Greek-language mathematical and astronomical treatise on the apparent motions of the stars and planetary paths, written by Claudius Ptolemy. One of the most influential scientific texts of all time, its geocentric model was accepted for more than 1200 years from its origin in Hellenistic Alexandria, in the medieval Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus.
