Earth's Moon

<< 3/12 < > Galileo false-color composite image of the Moon. The image was created using 3 exposures through different filters. The exaggerated color helps determine surface composition (blue is titanium-rich, orange lower titanium, purple pyroclastic, red iron and titanium poor). Mare Tranquillitatis is the blue area at right, Oceanus Procellarum is the blue and orange area on the left, the 85 km diameter Tycho crater is at bottom center, and Copernicus crater is just above and left of the center of the image. The moon is 3,476 km in diameter and north is up. (Galileo, P-41491)
