Moons aren’t just “extra” space rocks. They’re worlds.

Our solar system is full of natural satellites—some bright and familiar, some strange and mysterious, and some so large they’re bigger than planets like Mercury. In Nature’s Satellites: A Kid’s Guide to the Moons of Our Solar System, readers ages 6–10 will explore the moons that orbit every planet, from the inner solar system all the way to the icy frontier beyond Neptune.

This fun, science-rich guide takes kids on a clear, planet-by-planet journey through:

• What moons are (and how gravity holds them in orbit)

• Why Mercury and Venus have zero moons

• Earth’s Moon and what makes it so special

• Mars’s two tiny moons, Phobos and Deimos

• Jupiter’s famous moon worlds, including Europa and Io

• Saturn’s incredible moon family, including Titan and Enceladus

• Uranus’s storybook-named moons

• Neptune’s strange moon Triton, which may have been captured long ago

• Pluto and Charon, a double-world partnership at the edge of the solar system

Along the way, kids will meet the “moon champions”—the biggest, the most volcanic, the iciest, and the most surprising moons we know.

Perfect for space lovers, young scientists, and curious readers, Nature’s Satellites turns the night sky into a map of real worlds waiting to be discovered.
