Quick Take
- Narration: Samuel West brings measured elegance to the scientific material, matching the BBC documentary pedigree of the source content.
- Themes: Solar system formation, planetary individuality, the conditions for life
- Mood: Wide-eyed and contemplative, the literary equivalent of looking up
- Verdict: A genuinely accessible and current tour of the solar system that earns its sense of wonder through specificity rather than vague gestures at the sublime.
There is a particular kind of awe that good popular science writing produces, not the shallow gasp of a fun fact, but the slightly destabilizing recognition that the ordinary facts of the world are stranger and more contingent than daily life requires you to notice. I finished most of The Planets during a long drive through an unusually clear night, and the chapter on Jupiter, twice the size of all the other planets combined but less substantial than the name suggests, landed with an almost physical force. Brian Cox and Andrew Cohen write planetary science the way the best nature documentary narrators speak it: with the authority of rigor and the generosity of people who genuinely want you to feel what they feel.
The book is a companion to the critically acclaimed BBC series, which means it is written to complement visual storytelling rather than to stand entirely on its own. Cox and Cohen approach each planet as a distinct world with its own trajectory, its own catastrophe or absence of catastrophe, its own relationship to the question of what makes life possible. Mercury as a victim of the sun’s expanding power. Venus as a planet that might have been lush and instead became a toxic oven. Mars as a world that lost its atmosphere and with it any chance it had. Each chapter is a kind of biography.
Our Take on The Planets
The book’s most useful quality is its currency. Planetary science has changed substantially in the last two decades, and a general reader whose mental model of the solar system was formed in school will find this updates essentially everything they thought they knew. Reviewers specifically noted that their knowledge was out of date and that the book corrected it in ways they found genuinely surprising. One reviewer was moved enough to purchase both the hardback and the BBC documentary series after the audiobook. That chain of enthusiasm from one format to another is a sign of writing that generates genuine interest rather than passive entertainment.
The chapter on Jupiter’s role in shaping the inner solar system is particularly strong. The argument that Jupiter’s gravitational influence was essential to Earth’s ability to develop life, by deflecting or capturing potential impactors, is one of those pieces of planetary science that sounds like science fiction until the evidence is laid out methodically. Cox and Cohen lay it out methodically. The influence of individual planets on each other’s histories is the most conceptually interesting thread in the book, and it pays off in the later chapters on the outer planets.
Samuel West and the Documentary Voice
Samuel West narrates with the measured, elegant delivery that BBC documentary culture has refined over decades. He does not editorialize, but he gives the prose the weight it needs. The writing has the rhythm of something designed to be heard, which makes sense given the material’s documentary origins, and West honors that rhythm without over-dramatizing it. At seven hours and forty-three minutes, the pacing allows each planet sufficient time without lingering past what the content warrants.
The audiobook works very well for this material. Cox and Cohen’s prose is rich but not overly technical, and the narrative structure of each planet as a discrete story means you can take a break between chapters without losing the thread. This is one of those books that rewards a listening pace slightly slower than your commute might allow, because the most interesting concepts need a moment to settle before you continue.
What to Watch For in The Planets
The book was published in 2019 and released in audio the same year, which means seven years of planetary science have passed since. NASA’s observations of Mars and the outer planets have expanded substantially since then, and the James Webb Space Telescope, launched in 2021, has changed our understanding of planetary formation and exoplanet atmospheres in ways this book could not anticipate. The core planetary science holds, but specific claims about what we know and do not know about particular planetary systems should be understood as the state of knowledge at the time of writing.
The book is a companion to the BBC series, which means it occasionally gestures toward visual elements that the audio obviously cannot reproduce. Cox and Cohen note in the synopsis that the series includes stunning NASA photography, and some of the descriptive passages feel most fully realized when they have that photography to anchor them. This is not a disqualifying limitation, but pure audio listeners should know the companion context exists.
Who Should Listen to The Planets
Anyone whose last serious encounter with solar system science was a school textbook will find this substantially updating and enriching. It is also well-suited to listeners who have watched the BBC series and want the prose companion, or to readers of Cox’s previous Wonders of the Universe who are already familiar with his style and approach.
Pure astronomy enthusiasts who are already current on planetary science literature may find the level of detail insufficient. This is popular science at its best, not a research-level treatment, and it is explicit about that positioning. The accessible language that makes it valuable to a general listener means it does not linger in the technical details that a specialist would want.
Frequently Asked Questions
Does this book require any prior science background, or is it accessible to a general listener?
Fully accessible to a general listener. Cox and Cohen write with clarity and without assumed technical knowledge, and the narrative structure, each planet as a biographical sketch, makes the material easy to follow even without prior astronomy background. Multiple reviewers with no science training found it illuminating rather than daunting.
The book was published in 2019. Is the planetary science still current?
The core content holds well, but seven years of additional research means some specifics have been refined or extended. The James Webb Space Telescope in particular has expanded our understanding of planetary formation and exoplanet atmospheres since the book’s publication. Read the 2019 material as the state of knowledge at the time rather than the absolute current picture, and consider supplementing with recent NASA summaries for the latest on Mars and the outer planets.
Does Samuel West’s narration add to the experience, or is it simply functional?
West’s narration is genuinely well-suited to the material. The BBC documentary context of the source means the prose has a spoken-word rhythm, and West honors that rhythm without over-dramatizing. His measured, elegant delivery keeps the sense of wonder in the writing without tipping into hyperbole. Several reviewers noted the book’s quality without specific objections to the audio presentation, which suggests the narration is doing its job quietly.
Is this book better read than listened to, given the visual nature of planetary science?
The audio works well because Cox and Cohen’s prose is designed to evoke rather than to display. They write as though describing something to someone who cannot see it, which is exactly the right approach for audio. The one trade-off is that the BBC documentary series includes NASA photography that the audio obviously cannot reproduce, so listeners who want the full visual complement should consider watching the series alongside or after the audiobook.
