The farside of the moon is always turned away from the Earth. Its appearance remained a mystery until 1959, when the Russian spacecraft Luna 3 was able to travel behind the Moon and send back the first photographs.
Although the farside looks similar to the moon’s nearside, there are obvious differences. It has few maria, because the lunar crust is thicker than on the nearside, making it difficult for lava to seep through into the impact basins left by colliding space rocks.
The north and south poles were the last parts of the Moon to be mapped. This was done by the Clementine spacecraft in 1994.
Mosaic maps, made by assembling the thousands of images that Clementine sent back, showed that some of the polar craters are permanently shadowed from the Sun’s rays.

The Moon (Latin: luna) is the sole characteristic satellite of the Earth, and the fifth most imposing satellite in the Earth's planetary group. It's the greatest characteristic satellite of a planet in the Earth's planetary group with respect to the span of its primary, having 27% the width and 60% the thickness of Earth, bringing about 1⁄81 its mass. The Moon is the second densest satellite f...

The color of planets depends on the spectrum of the star’s light, which astronomers can easily observe, and filtering of light by air and water, which the author and her colleagues have simulated based on the likely atmospheric composition and it’s own effects.
