It has been announced on the SpaceDaily website that the committee was unanimous in defining a "Planet" as a body big enough to round itself off gravitationally, and whose shape is determined by hydrostatic rather than rigid forces.
Pluto remains a planet under this definition. All seven members of the committee are reported to be in complete agreement on this. And this will be the draft submitted to the IAU. They report that there are twelve known planets in our solar system under this definition. |

They report that there are twelve known planets in our solar system under this definition. Spacedaily claims that Charon makes the cut as a planet. I don't see how, since the body has to be in orbit around a star. It seems like they are saying that if the barycenter is outside either body (or something like that) then both bodies are planets. Seems kinda silly to me. Worst. Definition. Ever. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
