What does uranology mean?
Uranology is the study of the heavens and the objects observed in them. It was historically used as a name for astronomy, particularly in formal and scholarly writing, but the modern term astronomy has largely replaced it. The word can refer broadly to the observation and scientific investigation of celestial bodies, their motions, and the structure of the universe. It should not be confused with astrology: astrology interprets celestial phenomena in relation to human destinies or events, whereas uranology concerns their scientific study. Uranology is also memorable because its Greek root, ouranos meaning “heaven” or “sky,” is also the source of related English words such as uranium, uranic, and uranography, as well as the planet Uranus. Although the word is uncommon today, it provides a precise historical link between the modern scientific discipline of astronomy and the older vocabulary of celestial study.

Uranology and Uranus share the same Greek root for “heaven” or “sky”—so one name points to the scientific study of the heavens while the other names a giant planet.

Where does uranology come from?
Uranology emerged in English during the early modern period from Greek ouranos, meaning “heaven” or “sky,” combined with the study-forming suffix -logy. Its development coincided with the increasing use of astronomy as a distinct scientific discipline. Related English forms such as uranium, uranic, and uranography come from the same Greek root, which also lies behind the name of the planet Uranus.
