213 cards
This deck offers a friendly starting point for anyone curious about space, covering the basics of astronomy and cosmology alongside a tour of our own cosmic neighborhood. You'll find cards on foundational concepts like what these fields actually study, as well as more specific topics such as the planets, the asteroid belt, the Kuiper Belt, and the Oort Cloud. There's also a dedicated focus on the Sun, exploring what it is, how old it is, what powers it, and how hot its surface and corona get.
It's well suited to beginners, students, or anyone who wants a refresher on the structure of the Solar System and the science behind the objects in it. If you're just dipping your toes into astronomy or preparing for a class, the questions are framed simply enough to build confidence while still touching on meaningful details. More casual learners will also find it a quick and approachable way to pick up the key vocabulary of the cosmos.
To get the most out of studying, try working through a small batch of cards each day rather than cramming everything at once, since spaced repetition helps the names and definitions stick far better over time. It can also help to picture the layout of the Solar System in your mind as you review, moving from the inner rocky planets outward through the gas giants and ice giants to the distant reaches of the Oort Cloud. Connecting each fact to that mental map will make the material feel more like a story and easier to recall later.
