Do you wonder if humans are the only beings who wonder if they are alone in the universe? Our Sun is a star. In the night sky are all kinds of stars, and orbiting those stars are planets like the ones in our own solar system. Some of those planets are too big to be habitable. Or too small. Too hot or too cold. Planet Earth is not too big, not too small, not too hot, and not too cold. It's just right - our very own Goldilocks planet. But there are other habitable planets out there besides Earth? And if there are...are they home to other beings like us? How would we interact with them. Follow a young girl as she explores these questions in this gorgeous book about the wondrous search for another Goldilocks planet. -- From dust jacket.
