The planets closest to the Sun -- Mercury, Venus, Earth, and Mars -- include the world we know and its closest neighbors. However, despite our proximity, these rocky, silicate-based planets still represent so many mysteries yet to discover. Through a trove of images and a narrative bursting with detail, The Inner Solar System imparts what is known about this small corner of the Galaxy, and piques reader interest in the unknown.
