Book Review: The Neptune File

The Neptune File: A Story of Astronomical Rivalry and the Pioneers of Planet Hunting

You might expect planet Neptune’s discovery to be worthy of a footnote, or a magazine article at most. Yet Tom Standage manages to bring alive a fascinating story with an entertaining cast of characters from the 19th century around this discovery.

Man has known about the first six planets since ancient times. They’re bright enough to be seen with the naked eye, and their movements across the sky clearly distinguish them from the stars.

Searching the sky with his advanced (for the time) telescope, amateur astronomer William Hershel discovers a seventh planet, Uranus, in 1781. This created a sensation among astronomers, and opened up the possibility of more planets in the sky.

While trying to compute the precise orbit of Uranus, astronomers noted something wasn’t quite right. It was speeding up and slowing down from where it was expected to be. Two astronomers, the brash Frenchman Urbain Le Verrier and the quiet Englishman John Adams begin undertaking the complex calculations to try and predict where the new planet should appear.

With the calculations underway, the race is on to actually find the new planet, an amazing achievement with 19th century technology. The acrimony and infighting resulting from the discovery also makes for a great story.
