Kant in the information age

So they say that a new planet called Sedna (2003 VB12) has been discovered. Therefore all astrological computations have to be redone and life takes a completely different course, right ? According to the discoverers, Mike Brown (Caltech), Chad Trujillo (Gemini Observatory) and David Rabinowitz (Yale) my life willl change course but for an unexpected reason. Sedna is not a planet, but a planetoid. It is just a large object in the inner Oort cloud, almost certainly not more massive than the rest of the Oort cloud put together. Maybe it is not even the largest one in this class. However they also argue on similar grounds that Pluto should be demoted to the status of planetoid and is just the largest Kuiperbelt object.

Astrologists of all nations, unite! Save the planets! If this continues what remains certain in life?
