Pickering Crater is a crater in the Phaethontis quadrangle on Mars, located at 33.1° south latitude and 132.5° west longitude. It is in diameter. Lava flow fronts are visible within the crater, and the source of the lava is Arsia Mons. The lava has flowed around the central peak of the crater.〔NASA SP-441: VIKING ORBITER VIEWS OF MARS, Viking Orbiter Imaging Team, 1980, (chapter 5 ) (Volcanic Features)〕 The crater was named after several people: Edward Charles Pickering, American astronomer (1846–1919); his brother William Henry Pickering, American astronomer (1858–1938); and Sir William Hayward Pickering (unrelated), New Zealand-American engineer (1910–2004).
