The Moon
The Moon is Earth’s only natural satellite—a rocky, cratered body about one‑quarter the diameter of Earth, orbiting at an average distance of approximately 384,400 km. It influences tides, stabilizes Earth’s axial tilt, and was formed about 4.5 billion years ago following a collision between Earth and a Mars-sized object.

Apollo 15 Panorama
05/08/2016
On July 31, 1971, Apollo 15 astronauts Jim Irwin and Dave Scott deployed the first Lunar Roving Vehicle on the Moon. Using it to explore their Hadley-Apennine landing site they spent nearly three days on the Moon while Al Worden orbited above. This digitally stitched panorama shows Scott examining a boulder on the slope of 3.5 kilometer high Mons Hadley Delta to the left of their electric-powered, four-wheel drive vehicle. The sun at his back, Irwin casts the strong shadow to the rover's right. The panoramic view extends farther right to the sunward direction, over Hadley Rille and lunar terrain, revealed in harsh, unfiltered sunlight. In total, the rover traversed 28 kilometers (17 miles) on the lunar surface. The Apollo 15 mission returned about 76 kilograms of moon rocks to planet Earth.
