A person who practices, studies, or professes astrology; someone who claims to interpret celestial bodies to predict the future or character.
From 'astrolog-' + '-ist' (noun suffix for practitioners). This is the most common modern form, becoming standardized by the 16th century and remaining the primary term for astrological practitioners.
Interestingly, 'astrologist' can mean both a serious scholar studying historical astrology and a tarot-card reader at a carnival—the word survived while its practice shifted from scientific to mystical!
