The brightest spots on dwarf planet Ceres are seen in this image taken by NASA's Dawn spacecraft
on June 6, 2015. This is among the first snapshots from Dawn's second mapping orbit, which is
2,700 miles (4,400 kilometers) in altitude. The resolution is 1,400 feet (410 meters) per pixel.
Well if this is the image, it's 1024 pixels wide; and the bright spots are about 80 pixels across...
that would make the spots 21.2 miles across. give or take a mile, confirming Glatt's earlier math.
