"The beloved children’s classic Goodnight Moon gets a celestial remix in this astronomy-themed parody. Telescopes, scientists, and satellites fill the recognizable great green room, and the book’s rhythmic verses and alternating color and black-and-white illustrations stay true to the original tenor and tone.

Goodnight Exomoonis perfect for tucking little stargazers in at night or as a companion to the original. Through it, children will learn a thing or two about micrometers, atmospheric balloons, and what exactly an exomoon is, anyway." - Foreword Reviews
