MESSENGER image showing Antoniadi Dorsum cutting across Geddes crater

Antoniadi Dorsum is a ridge on Mercury at 25°06′N 30°30′W / 25.1°N 30.5°W / 25.1; -30.5, approximately 359 km in length. In 1976, it was named by the International Astronomical Union after Eugène Michel Antoniadi.[1]

Antoniadi Dorsum cuts across the crater Geddes. The same trend of ridges continues to the north, where it is called Endeavour Rupes near the crater Holbein, and beyond that, it is called Victoria Rupes, which cuts across the crater Enheduanna.
