Our friend Dr. John Johnson and his team have discovered some new planets!

John Johnson of the University of California at Berkeley and his colleagues presented the findings here today at a meeting of the American Astronomical Society (AAS).

Astronomers don’t directly spot extrasolar planets, but rather look for stellar wobbles caused by orbiting planets. The planet’s size and distance from the parent star affect how strong or weak of a wobble, and more sophisticated techniques for measuring the stellar wobbles has led to an ever-lengthening list of such outer planets. Now they can detect wobbles of a meter per second compared with the 10-meter limit just 15 years ago.

Previously, JJ found a planet with a 2.1 day orbit!
