Stickney (crater)

Stickney is the largest impact crater on Mars moon Phobos. Its diameter is 9 km. Thus, the crater takes up a considerable part of the surface of about 27 × 22 × 18 km, a big moon. Stickney is located on the middle of the western edge mars -facing side of the moon.

The crater is named after Chloë Angeline Stickney Hall, the wife of the U.S. American astronomer Asaph Hall discovered the two moons of Mars, Phobos and Deimos. The naming of the crater took place in 1973 after shots of the probe Mariner 9

Stickney has in its interior a smaller impact craters resulting from a later impact and measures about 2km in diameter. This was baptized in 2006 Limtoc, after a character in Gulliver's Travels.

Radiating pattern of Stickney appear likely grooves and crater chains. However, more recent findings of the Mars Express spacecraft, according to this have no causal connection to Stickney, but could have been formed from material derived from impacts on Mars. Inside Stickney has a distinct stripe-like texture that comes from rock slides, of material that has slipped into the crater.
