The (http://www.jpl.nasa.gov/news/news.php?release=2015-384) first images from Dawn's closest orbit to Ceres focused on the southern hemisphere and the Gerber Catena crater chain
The crater chain
which runs beyond the southern tip of Muller in a relatively straight line towards Ptolemaeus appears to be continuous along the crest of the southern wall of Muller.
Last year, Bottke and his colleagues proposed that a crater chain
might develop when an object passes so close to Earth it almost scrapes the surface.
During the 1960s, when human and spacecraft scrutiny of the Moon amplified the need for many new names, selenographers extended Latin's use to other landform types such as catena, dorsum, and rupes, for crater chain
, ridge, and scarp.
Another mysterious feature is the Davy crater chain
The best examples are a nameless straight line that cuts across the northeast edge of the crater Brenner, and a crater chain
southeast of Riccius.
The Davy crater chain
(marked on some Moon maps as Catena Davy) is a 45-km-long alignment of more than a dozen small craters, most of them 1 to 2 km wide.
THE NECTARIS REGION IS BLESSED with the magnificent crater chain
of Catharina, Cyrillus, and Theophilus.
Using these statistics, Bottke and his colleagues find that the lunar surface should bear only a single crater chain
and the Earth's none at all.
Imbrium does have radial structures extending in many directions, with tightly spaced secondary crater chains
prominent around the crater Ptolemaeas to the south.

Supporting evidence comes from a study of tightly packed crater chains
on two of Jupiter's icy moons, Ganymede and Callisto.
