While not a traditional textbook, I’ve included Welcome to the Planets, a website from NASA because of its inspirational photos of the planets as well as the wealth of information included with each of the photos. Along with extensive information on the planets, there is a section on NASA’s various missions and a glossary of astronomical terms, important historical figures and figures from mythology.
