You are bidding on a copy of Discovering Astronomy, 3rd Edition, by Robbins, Jefferys and Shawl, 1995 in used but good condition.  

Uses a discovery approach which encourages readers to be active rather than passive learners. Organized in the way astronomy developed—from observations to an understanding first of the solar system and later of stars and galaxies.
