헤벨리우스는 태양의 흑점을 관측하였고, 1642년에서 1645년까지의 4년 간 월면 지도를 만들었으며, 달의 경도상 칭동을 발견하여 그 결과를 Selenographia, sive Lunae descriptio (1647년)에 발표하였다.
Hevelius made observations of sunspots, 1642–1645, devoted four years to charting the lunar surface, discovered the Moon's libration in longitude, and published his results in Selenographia, sive Lunae descriptio (1647), a work which entitles him to be called "the founder of lunar topography".
