The Moon’s Huge Tycho Crater

A new photo of the moon’s huge Tycho crater taken at sunrise by NASA’s Lunar Reconnaissance Orbiter satellite in orbit around the moon on June 10, 2011, shows haunting dark shadows spreading out across the lunar surface.The pitch-black patches loom behind the Tycho crater’s central peak complex, which is about 9.3 miles (15 km) wide from southeast to northwest.Tycho crater is named after the 16th century Danish astronomer Tycho Brahe (1546-1601).The crater stretches about 51 miles (82 km) in diameter, with the summit of its central peak 1.24 miles (2 km) above the crater floor. The rim of the crater is about 2.92 miles (4.7 km) above its floor.
