The Moon is in synchronous rotation with Earth, always
showing the same face with its near side marked by dark volcanic maria that
fill between the bright ancient crustal highlands and the prominent impact
craters. It is the most luminous object in the sky after the Sun. Although it
appears a very bright white, its surface is actually dark, with a reflectance
just slightly higher than that of worn asphalt. Its prominence in the sky and
its regular cycle of phases. Source
