The 17th-century astronomer who kept a roughly 20-year continuous record of the positions of the Sun, Moon, and planets was Johannes Hevelius.
Hevelius was a Polish astronomer, mathematician, and brewer who made significant contributions to the field of astronomy during the 17th century. He meticulously observed and recorded the positions of celestial objects, publishing his observations in his monumental work titled "Prodromus Astronomiae" in 1690. This work contained a detailed star catalog, lunar maps, and records of planetary positions, including those of the Sun and Moon.
