Yes, it is possible. If the ten year old writes a good book with description and something original. You need an imagination to do that. I'm sure there is a ten year old out there that wants to be or is a famous author. You can become an author at any age really, as long as you can write and spell. But I doubt anyone under 10 or 11 really wrote a book really good. Most authors are over the age of 20.
