A facinating book - Ruku Banerji

This is a review of a book "How did we find about Pluto," by Isaac Asimov. Pluto was discovered by a poor farmer's son who only had a tenth grade education. Read this book to see how this surprising event took place. The book tells about Pluto's size, what led to its discovery, and why it needed investigation. An error in the observation of the orbit of Uranus caused the discovery of Pluto. This occurred because of another gravitational pull, which was not explained. Therefore it was believed that another planet existed. Eventually Neptune was found. Still a small error remained. This was when Clyde Tombaugh discovered Pluto in 1930.You will be astonished by the reading experiences you will get from this book. Isaac Asimov's writing is captivating and full of amazing facts. Such as Pluto being named by a little girl. In a way Pluto was an appropriate name because Pluto means "The God of the Dark Underworld," in Greek myths. Pluto received little sunlight since, it was the outermost planet from the sun. However Pluto does cross Neptune's orbit and becomes the eighth planet from the sun.I recommend this book to readers who have curiosity in astronomy, yet it would strike interest in anyone. This book provides you with amazing information about Pluto's orbit and its moons. It is written in a simple but extremely interesting style. This book might surprise you many times until you finish.
