Severina Crater

This image shows Severina crater. This is the large crater, approximately 25 kilometers (15 miles) in diameter, visible at the top of the image. Severina crater has a fresh, sharp rim and a smaller, presumably younger, crater on its rim.

There is an interestingly shaped small crater within Severina. This crater is roughly rectangular in shape, possibly because it is the result of two craters merging together or possibly because it is the result of erosion and slumping of one crater.

This image is located in Vesta’s Rheasilvia quadrangle, near Vesta’s south pole. NASA’s Dawn spacecraft obtained this image with its framing camera on Oct. 22, 2011 from a distance of 700 kilometers (435 miles).
