“A cheerful introduction to outer space.”—Booklist

“Supplemental tidbits ('Ouch! Asteroids and comets often hit this planet,' [McDonald] writes about Mercury) offer additional details to pique the interest of children just hearing about Earth’s cosmic neighbors for the first time.”—Publishers Weekly
