If a third-grader were to ask you how many planets there are in our solar system, how would you answer? Back before August of 2006, it would be pretty simple -- nine: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Ceres, which is found between Mars and Jupiter, was once considered a planet, but in 1850 was reclassified as an asteroid.

Growing up in the 1970s and 80s, I looked forward with excitement to the possibility that they would, some day, discover a tenth planet, way out there in the icy wastes beyond Pluto. In 2005, they announced just that -- the discovery of the body now known as Eris, just a tad bigger than Pluto, but three times farther away from the Sun.

And then, after lots of arguing back and forth, the International Astronomical Union (IAU) in August of 2006 decided to lump Ceres, Pluto and Eris into a special new category of their own, the "dwarf planet". So now, you'd tell that third-grader that there are eight planets -- unless you include the dwarfs.

Basically, the scientists are still arguing about exactly what they mean by a "dwarf planet". Meanwhile, author David A. Aguilar, along with his publisher, National Geographic, made his own decision -- as shown in the newly released book "11 Planets: A New View of the Solar System". I first learned about it when National Geographic announced that a girl named Maryn Smith, of Montana, came up with a nifty new mnemonic for learning the 11 planets: "My Very Exciting Magic Carpet Just Sailed Under Nine Palace Elephants". This appears at the very start of the new book.

Now, I'm a bit older than the target age group of ages 9 to 12, but enjoyed flipping through the pages. The book does an excellent job of giving the basic solar system layout in easily understood terms. First, there's the four terrestrial planets, then Ceres and the asteroid belt, then the four gas giants, and finally Pluto, Eris and the Kuiper Belt. And a little bit about the Oort Cloud, meteors, comets and planets around other suns. And our own Sun, of course.

Each section has a little discussion of the god, or goddess, the planet was named after (such as Ceres, the goddess of agriculture), along with nice drawings of the planet and its moons, if any. Included are some interesting facts, such as Jupiter's Giant Red Spot having existed for hundreds of years, or that Uranus is on its side, not more or less upright like the other planets. There are separate sections for Earth's moon, as well as the moons of Jupiter and Saturn. In back is a handy glossary and a table showing how much children of various sizes would weigh on various planets -- at least, those with a solid surface.

To give your budding astronomer some idea of the relative sizes of the planets, there's a fun list of ingredients you can buy from the store (a grapefruit, an orange, peas, a cherry tomato, a grape, some sugar, baking soda and salt) and how you can lay them out -- if you don't mind walking 1000+ yards to get to where Eris would be on that scale.

The one thing that might prove controversial is the author's decision to actually number the dwarf planets in among the bigger ones. Thus, Ceres is the fifth planet, Pluto the tenth and Eris the eleventh. Aguilar skips the more technical aspects of the IAU's decision, such as the fact the dwarf planets "fail to clear their neighborhood". He prefers to simply classify the planets by their size: small, medium and large. Given the book's target audience, that's just as well. Personally, I like his approach.

As more dwarf planets are added to the list, as is very likely, it may become increasingly unwieldy. I doubt anyone but the most die-hard future astronomer would want to memorize fifteen or twenty planets, never mind several dozen. But eleven is a nice number, and will do for now.

I bought this book for my daughter a few months ago when she turned 5, and she loves it. It has beautiful illustrations and only one page with info per planet (and sometimes another page for the planet's moons), so it's easy to read. The language is simple enough for a little kid to understand. It also talks about comets, Oort clouds and other solar systems. I like it so much that I've bought a few more for birthday presents.

Recently, modern astronomers came to a new consensus on how to view the solar system: the relatively tiny celestial body Pluto no longer qualifies as a planet, but is rather a "dwarf planet", and at least two more celestial bodies in our solar system (Ceres and Eris) deserve to be called "dwarf planets" as well. 11 Planets: A New View of the Solar System is an up-to-date look at the planets for inquisitive young minds, filled with fun facts about the eight planets, Pluto the dwarf planet, various planetary moons, Ceres and the asteroid belt, the Kuiper belt and Eris, and more. Illustrated with space photography as well as breathtaking artwork, 11 Planets is a simple yet fascinating look at the scientific wonders beyond Earth, highly recommended for children's library collections.

This is a beautiful book I keep on my coffee table. I'm very happy with it.

48 pages, Grade 3-8 - An exciting title for the astronomic-oriented, this book updates readers about our solar system from nine planets to eleven and the easy-to-follow reclassifications of them: Rocky/Terrestrial: Mercury, Venus, Earth, Mars; Gas planets: Jupiter, Saturn, Uranus, Neptune, and Dwarf planets: Ceres(new), Pluto and Eris(new). In double pages, 11 PLANETS presents each planet with illuminating photographs, digital paintings, and many visually impressive artworks and fast fact charts as well as paragraphs of texts that both informs and delights. The memory trick to remember the new planets in order among many other humorous lines makes my kid laugh really hard. We have never learnt so much so fast about our solar system and author/illustrator David A. Aguilar has brought the planets from the sky to our fingertips in the most fascinating way.

Really? 11 planets? I'm still trying to wrap my head around the whole Pluto is a dwarf planet thing, then I find out there's two new dwarf planets called Ceres and Eris. Did you know that? I sure as heck didn't!

First of all, I enjoyed the format of this book. Aguilar gives you an introduction to the `new' solar system, tells how it is formed, discusses the Sun, then breaks down each planet. Planets such as Earth, Jupiter and Saturn have additional information that tends to include information on moons and meteorites. Quite frankly, I learned a lot from this book! That doesn't mean I'll remember it, but I will remember this book because of an additional feature that I just adored: it gives you the name of the Greek or Roman god whom the planet is named after (Sun = Apollo) with a bit of additional information on that deity. I love mythology, so this was a great hook to keep me interested. And although the information is necessary and presented in an easy-to-access manner, it still bored me. I don't think this is actually the fault of the author, more of a lack of serious interest on my part.

Teachers, this could be a great way to combine a lesson on mythology with how it still influences us today. Obviously it's also a great introduction to our Solar System.

Notes on the Cover:
A big 11 with the sun bursting from behind while the 11 planets are lined up. Kudos to you if you can spot all 11 (kids will love doing that, 3 are tiny!)

This is the WORST BOOKS EVER!!! It says that PEOPLE ARE MADE FROM STAR DUST!!!--- DO NOT BUY THIS BOOK! SO much weird stuff said in this book!! BEWARE!!!
