Hello, World! Kids' Guides: Exploring the Solar System

Over half a million children own the Hello, World! Solar System, and parents have praised its easy, but stimulating facts, conversational tone, and bright, cheerful art. But, what about the Hello, World! Child, who is older and ready for picture books? Now there's Hello, World! Kids' Facts, which picks up where the mega-successful book series left off, at a higher reading level and a deeper exploration into each topic.

On each page of Exploring the Solar System, readers will find a variety of ways to learn:

• Fascinating details about each of the planets, including up-to-date information such as NASA's Perseverance rover and Ingenuity helicopter, which landed on Mars in 2021 - accompanied by bright illustrations.
• A panel of facts about each planet for kids who love data, with information about the planet's size, distance from the sun, length of days and years, and more.
• A running graphic that shows each new planet's place in the solar system relative to the sun.
• A question on each page that asks the reader to think about the planets in relation to themselves, such as "Would you like to live on a planet with a long winter or a short winter?" and "What would you bring on your Mars rover?"
