↑ Along the terminator are visible the moon's largest known impact crater, Gertrude, at upper right and several enormous canyon-like grabens (the Messina Chasmata above, Belmont Chasma near bottom) at lower right.
↑ Surface gravity derived from the mass m, the gravitational constant G and the radius r : Gm/r².
↑ Escape velocity derived from the mass m, the gravitational constant G and the radius r : √2Gm/r.
