Space is the rare subject where a child's appetite outruns the books available. Most titles fall into one of two traps: a labelled diagram of the solar system with no story, or a story that uses a rocket as scenery and could just as easily have been set on a bus.
The eleven below avoid both. They are sorted by the age they actually land at rather than the age printed on the back, which tends to be optimistic.
What makes a space book worth rereading
Three things separate the ones that get requested nightly from the ones that get read once.
A character who wants something. Facts about Jupiter are interesting for one reading. A child who wants to reach the moon and cannot is interesting for thirty. The best space books for young children are barely about space at all; they are about wanting something enormous.
Scale a child can feel. Saying the moon is 384,000 kilometres away means nothing at four. Showing a ladder that is not long enough means everything. The books that work translate distance into something physical.
Real detail, in small doses. Children who love space love the specifics: the name of the rocket, what astronauts eat, why they float. A story that drops in two or three accurate details earns more rereads than one that avoids facts entirely or one that is nothing but facts.
Ages 3 to 4
Papa, Please Get the Moon for Me by Eric Carle. A father fetches a ladder and climbs to the moon for a daughter who asks. The pages fold out to enormous size at the crucial moment, which does more to convey scale than any diagram. Still the best first space book there is.
Roaring Rockets by Tony Mitton and Ant Parker. Bouncy rhyme, bright flat art, a rocket launching and landing. Not remotely a story, but it is the one three-year-olds ask for again immediately, and the rhythm makes it easy to read aloud for the fortieth time.
Look Inside Space by Rob Lloyd Jones. A lift-the-flap board book. Flaps are what make nonfiction work at this age, because they turn reading into something the child does with their hands rather than something done to them.
Ages 4 to 6
How to Catch a Star by Oliver Jeffers. A boy wants a star of his own and tries increasingly hopeless methods to get one. Spare text, generous white space, and an ending that is quietly clever rather than triumphant.
The Darkest Dark by Chris Hadfield. A young Chris Hadfield is terrified of the dark until watching the Apollo 11 landing reframes darkness as the thing space is made of. Written by an astronaut who commanded the International Space Station, which children find impressive once you mention it. The rare book that does two jobs at once, since it is also the best bedtime-fear book on this list.
Astro Girl by Ken Wilson-Max. A girl spends the day acting out everything an astronaut does while waiting for her mother to come home, and her mother turns out to be the astronaut. Warm, simple, and one of very few picture books where the astronaut is a working parent.
There's No Place Like Space by Tish Rabe. The Cat in the Hat's Learning Library entry on the solar system, in Seuss-style rhyme. This is the one that actually teaches the planets and sticks, because the rhyme scheme does the memorizing.
Ages 6 to 8
Mousetronaut by Mark Kelly. A small mouse turns out to be the only crew member who can retrieve something from a tight space. Written by a NASA astronaut and based on a real mouse that flew on a shuttle mission, which is exactly the sort of fact this age group repeats to everyone for a week.
Moonshot: The Flight of Apollo 11 by Brian Floca. The Apollo 11 mission told with real procedure and real hardware, in a text that still reads aloud beautifully. The best answer for a child who has moved past wanting stories and into wanting to know how it worked.
Zoo in the Sky by Jacqueline Mitton and Christina Balit. Constellations as the animals they are named after, in gold-flecked art. Works best if you read it and then go outside, since the payoff is finding one.
Professor Astro Cat's Frontiers of Space by Dominic Walliman and Ben Newman. Dense, handsome, genuinely informative, and the natural next step for a child who has exhausted the picture books. Closer to a reference book with jokes than a story, so it suits the top of this range.
Where a personalized book fits
None of the above stars your child, and for the classics that is entirely the point. But the pattern of what works is worth noticing: the strongest titles on this list are about a specific child wanting something out of reach.
That is the one thing a personalized story can do that a published book cannot, because the child wanting the impossible thing is your own, with your own child's name, age and favorite animal along for the trip. Our personalized space adventure puts them in the pilot's seat with a lesson you choose. It belongs alongside the books above rather than instead of them, and it works best as the one they get to be in after the others have set the appetite.
Frequently asked questions
My child wants facts, not stories. Where do I start?
Look Inside Space at three or four, There's No Place Like Space at five, Professor Astro Cat at seven. Skip the picture-book narratives entirely if that is genuinely the preference, since forcing a story on a facts child is how reading becomes a chore.
Is there a good book about a female astronaut?
Astro Girl is the strongest for the younger end. For six and up, biographies of Mae Jemison and Valentina Tereshkova are widely available and generally better written than the average celebrity picture book.
What about books on the planets specifically?
Be aware that anything printed before 2006 lists nine planets, which confuses children who have already learned otherwise at school. Check the copyright page on secondhand copies.
How many space books is too many?
There is no such thing, but variety of type beats variety of title. One story, one lift-the-flap, one factual reference and one where the child is the hero covers the whole appetite better than four narrative picture books.
What if my child is into dinosaurs instead?
The same principles apply, and the same personalization does too. We run a dinosaur version built the same way.
