astronomer who compiled an atlas of the Moon (Selenographia, published 1647) containing one of the earliest detailed maps of its surface as well as names for many of its features. A few of his names for lunar mountains (e.g., the Alps) are still in use, and a lunar crater is named for him. Hevelius also made a catalog of 1,564 stars, the most comprehensive of its time, and a celestial atlas in which several constellations, now accepted, were shown for the first time. After his death, the catalog and the atlas were published together (Prodromus Astronomiae, 1690) by his wife, Elisabetha, who had collaborated with him in his observations.
