Landslides have produced scalloped margin domes on this body that resemble a round body surrounded by legs, and were thus formerly known as "ticks." The Japanese probe Akatsuki is planning to visit this body in 2016. Brightening of the radar reflections off its surface is posited to be due to deposition of pyrites and sulfides in highland regions such as (*) Lakshmi Planum. It has only a weakly induced magnetic field; the lack of a dynamo-generated field is thought to indicate a lack of core convection, perhaps due to its lack of plate tectonics.
