(2) K-3 Illustrated by Jessica Lanan. Manley presents a smart, careful, and thorough discussion of exoplanets. Lanan's illustrations take the concepts to the next level; the choices of scale, color, and detail in her planetary landscapes make visible the text's content. The clever use of a parallel visual narrative, which features a (brown-skinned) girl and her family visiting a planetarium, situates the images of possible other life-supporting worlds in that character's imagination. Timeline, websites. Bib.

(4) K-3 Galaxies presents a guide to our universe of stars and galaxies and includes a rudimentary history of astronomy and telescopes. Planets introduces each planet and the basic concepts of planetary motion. While these two lightly updated editions feature Gibbons's inviting, scientifically rigorous illustrations, two depictions of the solar system in Galaxies still show the outdated nine-planet model. Review covers these titles: Galaxies, Galaxies! and The Planets.

A list of stats for each covers size, weight, surface temperature, and other attributes. Large illustrations with a retro aesthetic, diagrams, and text boxes provide additional information for a browsable, if somewhat crowded, presentation. Glos., ind.

(3) K-3 In this humorous presentation of solar system facts, the sun is a "star" (as in celebrity) surrounded by admiring planet "fans." The anthropomorphized planets, amusingly illustrated as cute emojis, joke their way through definitions that include day and night, the seasons, the water cycle, and photosynthesis. Additional facts and definitions are found on the closing endpapers. Glos.

Simon explains how new techniques and technologies have accelerated astronomers' search for Milky Way planets beyond our own solar system, leading to the discovery of planets that might be within the "habitable zone" of distant stars. Large, excellent images of telescopes, near and distant planets, and the imagined surfaces of possible future discoveries are included. Websites. Glos., ind.

(3) K-3 Illustrated by Melanie Demmer. This picture book approaches the science behind Pluto's demotion to dwarf planet with cartoonish art and humor. Once happily in the "famous nine," Pluto is crushed to hear from smug Saturn and Jupiter that he's deemed too small to remain a planet. A search for acceptance among asteroids and comets proves fruitless until Pluto finds his people, so to speak. An endnote adds scientific context to the silliness.

(4) 4-6 George's Secret Key series. Illustrated by Garry Parsons. This fifth installment finds friends George and Annie at an elite space camp battling an evil villain intent on ruling the solar system. Character development and plot come second to the science, but lots of danger, robots, and a peek at Jupiter's moon Europa should hold series fans' attention. As usual, relevant scientific essays appear throughout but may be beyond some readers' interest level.
