Hedin (crater)
This crater has a deteriorated outer rim that has been worn down and reshaped through impact erosion. Several small craters lie along or near the rim, including Hedin F to the northeast and Hedin H to the southeast.
The interior floor has been scored by the impact event that created the Mare Orientale to the southeast. But these features are cross-hatched by a pair of linear rilles that follow a path towards the southeast. Only a section of the floor along the northwest rim is relatively level, retaining the low albedo of ground that has been resurfaced by lava.
This crater is sometimes referred to as "Sven Hedin" in older publications.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Hedin.
