SkyTools is an "Observing List" centric observation planning tool and can be found at http://www.skyhound.com/skytools.html

The attached chart is an example of the charting feature in SkyTools and I have copied and pasted the "Information Panel" which is a separate function.

Great stuff Dennis. This is really going to set the cat among the pidgeons. Is it or isn't it. If they (whoever they are ) decide it isn't a planet then maybe Pluto won't be considered a planet anymore, and we're back to 8. I'm really looking forward to the "discussions" that are going to come out of the scientific community. If they decide that, "yes it is a planet" then won't that add more weight to making Sedna and Quoaor planets as well? Or maybe "they"'ll have to invent a new catagory of planetessimal to take into pluto et al.

Exciting times

I searched this topic yesterday and the following link gives the best answer.
Basically it states common sense prevails.

My opinion......If I cant find it in my scope its not a planet

UB313 not exactly the most exciting name I have ever heard. Seeing it's the third largest object in the Kuiper belt means we could end up with a host of planets.
I hope they call it "Pele" after the greatest human on the face of this planet.
