New Exo-planet Discovered

  1. Feb 11, 2005 #1
    Read about the discovery of the smallest (1/5th of the Pluto-size) exoplanet. This was just posted on PhysicsWeb, so it is very fresh. I also included some explanatory links, the first goes to the webpage of one of the discoverers...

    that's interesting
    four modest-size planets going around a pulsar
    thanks for posting the link, marlon.

    I guess that it is easier to detect small wobbles by a pulsar
    because one can do dopplershift analysis very accurately
    using the clockpulse of the pulsar

    it makes one hopeful that there may be plenty of modest-size planets circling ordinary (not pulsar) stars as well

    Twenty percent the size of Pluto... wow! That's quite amazing.
