Autor: Stern, S. A., White, O. L., Grundy, Wm., Keeney, B. A., Hofgartner, J. D., Nesvorny, D., McKinnon, W. B., Richardson, D. C., Marohnic, J. C., Verbiscer, A. J., Benecchi, S. D., Schenk, P. M., Moore, J. M.

We report on a study of the mounds that dominate the appearance of Kuiper Belt Object (KBO) (486958) Arrokoth's larger lobe, named Wenu. We compare the geological context of these mounds, measure and intercompare their shapes, sizes/orientations, ref
