The Terrestrial Planets: Mercury, Venus, Earth, and Mars
The rocky bodies of the inner solar system are diverse worlds. Tiny Mercury lies close to the bright, hot sun. Venus is covered in thick clouds that rain acid. Earth is lush and home to life. And Mars, while distant and cold, could be humanity’s next destination in space. The Terrestrial Planets introduces readers to these places and explains how people are exploring them today.
