Far Side Lunar Crater

An Eroded Far Side Crater Coated in Fresh Rays

Spanning 100.74 kilometers on the far side of the Moon, the heavily worn crater Ventris is marked by multiple subsequent impacts and draped in bright ejecta rays from its southern floor.

Geological Chronicle

Ventris is an impact crater measuring 100.74 kilometers in diameter on the far side of the Moon. It is located between the crater Schliemann just to the northwest and the large Keeler slightly farther to the southeast, with Vening Meinesz lying one crater diameter to the northeast.

Since its formation, the crater has been heavily worn and eroded by subsequent impacts. Multiple craters lie across the rim and interior, including Ventris C across the northeastern rim and Ventris A in the northern part of the floor. The southern floor contains Ventris M, a fresh crater whose small ray system and high albedo spread a skirt of ejecta across most of Ventris, with narrower rays extending farther northwest and southwest.

Prior to its official designation, the crater was known as Crater 301. The feature was formally named by the IAU in 1970 after British architect and decipherer Michael Ventris, who deciphered the Linear B Cretan script.
