Radar showed that a hollow space encompasses the entire circumference of the pit at a depth of roughly 40 meters below the lunar surface.

The studies noted that the pit floor appeared to extend underground beyond the opening by at least tens of meters, potentially indicting the presence of a cave conduit.

[1] Research of the cave based on radar data estimates that the size of the underground portion is no less than 130 feet (40 meters) wide extending to the western side.

[7] Radar studies conducted by an astronomical research team led by University of Trento professors Leonardo Carrer and Lorenzo Bruzzone and published on 15 June 2024 used radar imaging from the NASA Lunar Reconnaissance Orbiter to determine the shape and structures of the pit and features connected to it.

[1][4] The researchers noted that the additional underground space connected to the pit could make it a potential host of a future lunar base due to the cave's protection from prologued exposure to the surface's environment, including from solar radiation, cosmic ray exposure, and micrometeorite impacts.
