Hilbert G (Moon)

Satellite Feature of Hilbert

Named after David Hilbert - German mathematician (1862-1943).

Hilbert is a lunar crater on the far side , just past the southeast limb. It lies just beyond the region of the surface that is occasionally brought into view due to libration, and so this feature cannot be observed directly from the Earth. The crater is attached to the southeast rim of the walled plain Pasteur, a formation nearly half as large again as Hilbert. To the southeast is the smaller crater Alden, while Backlund lies to the west-northwest. (wikipedia entry)
