Phobos shape
Webb3 feb. 2024 · We determined the gravity equipotential ellipsoid of Phobos during its orbital decay and studied the evolution of surface ellipsoidal heights. We found that the equipotential ellipsoid closely fits the body shape near 3.6 Mars radii. Meanwhile, the height distribution resembles Gaussian at 3.3 Mars radii, suggesting equilibrium of … WebbShape modeling: SPC has been used successfully to develop high-resolution shape models of a variety of small bodies, including Eros [9], Itokawa [10], Phobos [11], Phoebe [12], Lutetia [13], and comet 67/P Chur-yumov-Gerasimenko [14], among others. The method is also integral to the altimetry and shape modeling efforts

There's been a debate about what caused these grooves. Some researchers suggested that Phobos was showered with debris from large impacts, and the debris carved the grooves into the surface.
