There Goes the Solar System

The new solar system
The International Astronomical Union/Martin Kornmesser

A committee of the International Astronomical Union, the body responsible for the naming of planets and other celestial objects, has decided to allow at least three new “planets” into the solar system.  The group made the recommendation after it was asked to resolve the Pluto controversy.

Pluto, once thought to be much larger in size, is actually smaller than a nearby non-planet.  With scientists discovering more and more “planetoids,” debate has been raging among astronomers over what objects deserve the name of planet.  Some scholars insisted Pluto should be removed from the category entirely, while others applauded the new system.


BBC News:

The IAU draft resolution recognises eight “classical” planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune - three “plutons” - Pluto, Charon and UB313 - and the asteroid Ceres.

Charon is currently described as a moon of Pluto, but because of its size some experts consider it a twin planet.

Professor Owen Gingerich, who chairs the IAU planet definition committee, said: “In a sense we’re demoting Pluto by taking it off the list of classical planets. But we’re promoting it by making it the prototype of this new category of plutons.”

Hmmm… new planets that have been there all the time.  Cannot get realistic weather one day ahead.

Starting to look like scientists don’t know much.  Speaking as a scientist, I can say I already suspected as much!

Yet we must, must, must, on pain of being labelled a heretic believe in global warming.

Despite the scientists and media predicting four cycles of global climate change (cooling, heating, cooling, heating) and death on a massive scale--- SINCE 1895!!!!  Yes 18 95… we are still here.

Perhaps the “con of man” is science afte all?

Good! The more the merrier!! Our solar system is getting crowded with at least 56 planets that are in fact, in our solar system! ehy not let these in. The bigger the better and we should explore these planets more and learn more about the stars! And in a way we are the universe so we are the univers wondering and discovering itself! which is a beautiful reality!

I’m glad they’re letting three new planets into the solar system. It’s not like they weren’t there already, or anything. Sort of like Columbus “discovering” America. The people who were here at the time already knew it existed.

A discussion with a British astrologer on a BBC podcast this morning revealed that astrological practitioners have been using Ceres for quite a long time in their calculations and predictions. He was glad the scientific world had finally caught up with them.

After all that study, couldn’t they have given Uranus a new name?  Cause I’ve seen Uranus, and it ain’t pretty.
