From: A newly revised estimation of bulk densities and examination of the shape of individual Ryugu grains
Optical and projected images of the largest Ryugu grain, C9000. a Optical image after the composite process; 5 × 4 images were taken horizontally, and 11 layers of the images were stacked. b Major (a: orange line) and minor (b: blue line) diameters of the ellipse (red line) that best fit the projected area (ROI) of C9000. c Maximum (af: orange line) and minimum (bf: blue line) Feret diameters of C9000. These two dimensions are not necessarily orthogonal. See text
