This beautiful Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on October, 14, 2015, shows us a portion (the Southern one) of the Terraced Rim of the large Impact Crater named Urvara (look at the upper left - Sx - quadrant of this view).


Urvara Crater is located in the Southern Hemisphere of 1-Ceres and, according to the new calculations made by NASA's Planetary Scientists, is roughly 106 miles (such as about 170,59 Km) wide. Furthermore, a number of medium-sized, ancient and Unnamed Impact Craters (with unusually-looking Surface Features and Peaks inside them) can also be seen all over the picture.


The original photo was taken from an altitude of approx. 915 miles (such as about 1472,5461 Km) from the Surface, with a resolution of roughly 450 feet (such as about 137,16 meters) per pixel.


This image (which is an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20128 - Dawn HAMO Image 65) has been additionally processed, extra-magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized (according to an educated guess carried out by Dr Paolo C. Fienga-LXTT-IPF) in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Dawn Spacecraft and then looked ahead, towards the Surface of 1-Ceres), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
