A Q&A with the Star* of our book, Sun *Get it? Star of our book?

Who is your favorite planet? And remember, this book will be read mostly by Earthlings.

Of course I don't have a favorite. Each is special--and kind of puny. That's like asking a human to pick a favorite fingernail.

You've been around for nearly 4.6 billion years, and are expected to shine at least 6 billion more. How do you stay so enthusiastic?

I like to keep moving. As you have read, I rotate. But also, about every 11 years, my poles change magnetic polarity. I also orbit the Milky Way--taking Earth and all my planets with me. That's a long trip--about 230 million years.

Do you have any advice for readers?

Yes. Never stare directly at me--even during a solar eclipse--because I can damage your eyes. You delicate earthlings can't handle my ultraviolet rays. Also, eat your vegetables. I helped grow them.
