Chapter 11 Summary
As soon as George and Annie pass through the doorway it disappears. Holding Annie’s hand, George feels them falling gently until they land on the surface of a comet. Annie points out she wasn’t lying, and George apologizes for doubting her.
She tells him that they will ride the comet as it passes by planets. Excited, George jumps and feels like he is floating away, though he slowly drifts back down to the surface. Annie hurries to him and explains that he weighs much less here than he does on Earth. She shows him the comet’s glowing tail. When George worries that the comet will melt, Annie explains that the sun causes some of the ice to evaporate, forming the tail they can see. George then asks what would happen if rocks from the comet fell toward Earth, Annie answering that they would burn in the atmosphere, creating a shooting star.
Suddenly, Annie tells George to sit and attach himself to the comet, warning that something might hit them. As the comet speeds forward, Annie asks George if he likes roller coasters. The comet seems to drop, but George doesn’t feel the motion—“he was starting to realize that things feel very different in outer space from the way they do on Earth” (103).
The first of two educational accompaniments explains the concept of mass, noting that “the mass of a body measures the force needed to move it or to change the way it moves” (98). It compares the mass and gravity of the Moon and Earth to show why objects weigh less on the Moon, and it introduces Einstein’s equation, E=mc2. The second section focuses on comets, describing them as icy bodies similar to snowballs that form tails when heated by the Sun. It also explains how comets can travel in looping orbits or can become “cosmic wanderers” that do not return.
Chapter 12 Summary
George, who had closed his eyes, opens them and sees Saturn. Annie teases him for being scared, boasting she saw the planet first. She explains Saturn is the second largest planet in the Solar System and mocks George for assuming Earth was the biggest—“The Earth is teeny-weeny, just like your silly little brain” (107).
As the comet passes near Saturn, George studies the planet’s rings. Reaching out, he manages to grab a small piece of rock and secretly slips it into his pocket before Annie notices. When she sees him moving around, he distracts her by asking several questions about the comet’s path. Annie explains that Saturn’s gravity pulled the comet into a turn as it passed by the planet. Looking out, George spots several of Saturn’s moons.
An educational section of the chapter discusses the Solar System—“the cosmic family of our Sun” (109)—outlining each of the planets and the three named dwarf planets. It also mentions the Voyager 1 mission, which explored the outer planets and continues traveling through space. A second section focuses on Saturn, explaining its size, position, gravity, structure, weather, and moons.
Chapter 13 Summary
George notices a bright spot in the sky and turns to ask Annie about it, but she is gone. Following her footprints across the comet, he finds her looking into a hole. Annie accuses George of being angry with her, which he loudly refutes. As they argue, geysers begin to erupt. They return to where they had been sitting, both pretending not to be scared.
They bright spot grows larger, and George realizes it’s Jupiter. He asks Annie about the planet—whether it has moons and if she has ever been there. The comet shifts directions as Jupiter’s gravity pulls on it. Annie points out the planet’s stormy Great Red Spot, and they discuss its many moons. George counts four large moons, but when Annie immediately agrees, he feels uneasy—“it wasn’t like Annie to agree with anything he said” (121). Annie shouts a warning that they are flying into an asteroid storm.
The chapter ends with an educational aside on Jupiter. It explains Jupiter’s size, position, gravity, and structure. The text also discusses its orbit and details about the Great Red Spot—a massive storm that has been active for centuries.
Chapter 14 Summary
As asteroids strike the comet, Annie says there is nothing they can do but ask Cosmos to bring them back. She screams as another rock hits, but when the noise suddenly stops, George realizes that Annie’s radio antenna has been broken. They can no longer hear or speak to each other or contact Cosmos. They cling to one another until the comet passes through the asteroid belt. However, more geysers erupt. They spot a small blue dot—Earth—in the distance. Using hand gestures, Annie informs George she can’t reach Cosmos. Just as he starts to lose hope, a doorway appears. Eric reaches through and pulls them back into his library, furious.
An educational aside focuses on the Asteroid Belt—a ring of rock bodies orbiting the sun between Jupiter and Mars.
Chapter 15 Summary
Back in Eric’s library, George faces Eric’s anger and almost wishes he was back on the comet. Eric sends Annie to her room before scolding Cosmos for allowing the children to travel in space. Cosmos insists he was only following commands, then warns he is going to “crash.” His screen goes dark. When George tries to apologize, Eric cuts him off, blaming him for putting Annie and himself in danger. George wants to protest—“it was Annie who had pushed them both through the doorway into outer space” (130)—but decides to stay silent.
Eric takes George home and speaks with his parents. Both children are grounded for one month, and Cosmos will be kept away from them from now on. George thinks the situation is unfair, but his dad tells him, “‘If this is the effect that technology has on you, you see how right we are to keep you away from it” (132).
Although he is glad to avoid Annie at first, George soon misses her. One day, he sees a sign for a science competition at school, with a new computer as the first-prize place. Excited, he decides to sign up, but has trouble choosing a topic.
Later, he runs into Annie while in the yard. Both are bored, and they quickly apologize to each other. Annie slips through the fence, and they hide together in Freddy’s shed. George explains his father is at a climate change protest—something he has grown embarrassed by—and Annie admits she is grounded from space travel until she is an adult. She tells George her mother is dancing ballet in Moscow but admits the truth—her mother is tending her ill grandmother—when George detects the lie. Annie also says Eric’s goal is to find a new planet where humans can live.
They talk about the science competition, which Annie will be attending but not participating in, saying, “‘I don’t want to win a stupid computer. If it was some ballet shoes, then that would be different’” (140). She suggests George make his presentation about space and says Eric could help him make sure it is accurate. When George’s mother approaches, Annie blurts out that George shouldn’t be in trouble; however, his mother is only bringing them snacks—broccoli muffins and pumpkin pie.
Chapters 11-15 Analysis
In these chapters, the space setting is rendered through tangible, child-friendly imagery while also engaging with The Importance of Science and Stewardship of the Earth. When George realizes that “things feel very different in outer space from the way they do on Earth” (103), the authors use sensory contrasts—silence instead of air, weightlessness instead of motion—to help readers imagine what space might feel like. The wonder George feels mirrors the wonder the story seeks to inspire in readers, while the factual accuracy grounds the adventure in scientific truth. Thematically, this expanded setting suggests that it is only by seeing the Earth from afar that George can begin to appreciate its beauty and fragility.
Space also becomes a symbolic landscape for growth. When George “reached out, snatched up the rock, and held it in his space glove—a real treasure from outer space!” (108), the object operates as more than a souvenir. The rock symbolizes George’s hunger for knowledge and his instinct to possess what he discovers. It introduces a subtle question about ownership, reflecting The Ethical Use of Knowledge and Technology. Holding a “treasure” from space satisfies George’s curiosity but also foreshadows the moral lessons to come about humility and responsibility. His gesture of taking rather than observing reminds readers that discovery carries ethical weight.
Each celestial encounter functions as both spectacle and lesson. The planetary descriptions, particularly the sequence around Saturn, combine scientific facts with narrative momentum. George “looked at Saturn with respect as the giant planet with rings shrank into the distance behind them until it was just a bright dot in the starry background” (112). The sentence fuses plot and instruction—George’s sensory awe complements the educational aside on Saturn’s size and structure. Through this technique, the novel turns the Solar System into a classroom.
The book’s structure reinforces this pedagogical rhythm. Short chapters keep pacing quick and tension high, while interspersed science sections allow readers to pause and absorb new information. Each chapter centers on a single idea—mass, gravity, comets, Saturn—linking George’s journey to scientific exploration. This rhythm also underscores the theme of the ethical use of knowledge, as learning unfolds step by step, through observation, reflection, and correction.
These chapters also deepen the emotional conflict between George and Annie, which reflects The Struggle to Be Understood. When Annie mocks him with, “you just don’t know anything at all, do you?” (111), her superiority frustrates George and exposes his feelings of inadequacy. However, their tension quickly reverses, revealing Annie’s own vulnerability. When she says, “You’re always angry with me. It doesn’t make any difference if I’m nice to you or not” (118), she voices her confusion and hurt, showing that both children feel misunderstood and defensive. Their miscommunication suggests that empathy, like scientific understanding, requires patience, perspective, and humility.
Their friendship continues to develop after they are separated. Initially, George is glad to be free from Annie, but later he “found himself looking for the flash of her golden hair” (132). This moment captures emotional maturation. George’s relationship with Annie models how understanding—of the world and of other people—requires both curiosity and compassion.
