This Dawn framing camera (FC) image of Vesta shows Canuleia
crater, which is the large, irregularly shaped crater in the top
left of the image. Canuleia’s average diameter is roughly 11
kilometers (6.8 miles) but it is clear in this image that the
diameter running from top to bottom is larger than the diameter
running from left to right. Other interesting features of
Canuleia include the diffuse bright material that is both inside
and outside of its rim and the ridges and gullies around its
rim. Also striking is the patch of dark material, with a rounded
end, that is located inside and outside of the crater’s bottom
left quadrant. Surrounding Canuleia are the distinctive curved
grooves and ridges of Vesta’s southern hemisphere. This image is
located in Vesta’s Urbinia quadrangle, in Vesta’s southern
hemisphere. NASA’s Dawn spacecraft obtained this image with its
framing camera on Oct. 27, 2011. This image was taken through
the camera’s clear filter. The distance to the surface of Vesta
is 700 kilometers (435
