Scientists tracking Sedna have recently discovered that it is larger and has a more interesting geography than previously thought:
Read more here.A recently discovered distant world in our solar system—named Sedna—has been the subject of considerable observation as of late. Scientists have been debating whether to call Sedna a "planet" or something else, such as a "Kuiper Belt object," "minor planet" or "planetoid."
The debate is about to heat up. Astronomers using observations from the International Space Station have concluded that Sedna is considerably larger than previously thought, with a mean radius of about 2400 km. That would make Sedna comparable in size to Mercury, greatly enhancing Sedna’s claim to planetary status.
Of more curious interest are anomalies in images of Sedna, which show changes to the Sedna’s profile as it rotates. There is a growing consensus that the anomalies are caused by eight immense mountainous masses on Sedna, approximately equidistantly spaced on the surface. Curiously, Sedna’s shape may prevent it from being deemed a planet. "The damned thing is cube-shaped, and everybody knows you can’t have a cube-shaped planet," said Astronomer Upton O’Goode, announcing the discovery.
O’Goode further reported that the images show that each of Sedna’s six “sides” has a different albedo, as if each side had a different number of dark patches on it.
"Einstein said that God does not play dice," O'Goode said. "Well, here at last is proof that Einstein was wrong."
