Shorty is a feature on Earth's Moon, an impact crater in the Taurus–Littrow valley.[2] Astronauts Eugene Cernan and Harrison Schmitt visited it in 1972, on the Apollo 17 mission.[2][3] It is the location of the famous "orange soil," which geologists believe to be small bits of rapidly-cooled molten rock ejected in a fire fountain.[2] It is about 110 meters (120 yards) in diameter and up to 14 m (15 yd) deep.[4]

Shorty Crater is about 14 m deep. Based on our investigations at the site and later examination of photographs, the impact that formed it penetrated, in order, regolith on the avalanche deposit, the avalanche deposit, regolith on a basalt flow, a basalt flow overlying and protecting the orange and black glass layers, the orange and black glass layers, regolith on a second basalt flow, and, finally, the upper portion of that second flow. Orange and black glass clods and basalt boulders are spread throughout the ejecta blanket surrounding Shorty.

— Apollo 17 Lunar Module Pilot Harrison Schmitt as quoted on the LROC Instrument website[4]

To the east of Shorty are Victory, Camelot, and the Apollo 17 landing site. To the southeast is Brontë. To the southwest are Lara and Nansen.

The crater was named after the character "Shorty" in Richard Brautigan's 1967 novel Trout Fishing in America, as well as to honor the genre of the short story with particular reference to J. D. Salinger.[5]
