The Planet That Wasn't

Summary: Articles from the dean of science writers
Review: This is yet another collection of Asimov's science essays for Fantasy and Science Fiction Magazine. He starts out with the title essay (about the theoretical planet Vulcan that caused perturbations in Mercury's orbit) and ends up talking about the existence of God. As he puts it, he goes from the least controversial essay to the most. All the essays date from the mid-seventies and aren't as dated as the last collection I read, though there is obsolete data about Pluto. As always, it's an easy read and informative.
