• Resumen

  • Every few years, the North Pole wanders a little closer to Alaska, then swings back again. It may only be a few meters a year, and it is certainly not noticeable from day to day. Here, Battersby discusses polar wobble which has been enough to puzzle stargazers for more than 100 years.
