10th planet. What, again?

We have so many stars which are planets we'd have a million of them.

 

Some people think that if this thing is a new planet then the moon should be called a planet as well., since its bigger then the new object. Or co-planet with earth.

 

I know many people who class the moon as a planet.

 

No, the moon (afaik) is a satellite, or a moon. Something that goes 'round a planet is a moon. Something that goes 'round a star is a planet. At least that's what I thought.

 

yeah, but how are you going to differentiate planet v. sun


there are some bisolar (I know it's not a word) systems how is the nomenclature going to work on that


am I the only person on earth who thinks nomenclature is silly as long as you get there?


and yes I know my communication skills are awful...... I don't care all as much as I probably should....

 

Differentiate a planet from a sun? Uh.... A sun is a star (hot ball of nuclear fusion) and a planet is something solid that flies 'round a sun. The interesting distinction is between an asteriod and a planet - both orbit stars, but an asteroid is hugely smaller. Some of these new 'planets' might better be called asteroids, because they're small and sit right in the middle of asteroid belts.

Not very unusual, really. Except in that we're here, obviously. That's pretty damn unusual!

how many planets do we have?

 

Yes, im sure thats how its scientifically defined. All i said was, i know many people who class it as a planet.

There has been speculation of a 10th planet for many years, now. There are even many people who believe that Pluto should be stripped of the "planet" title, because of it's size and irregular orbit pattern. Pluto belongs to the Kuiper belt, and they've already discovered many objects in the belt that are much larger than Pluto, and make much more sense to be classified as planets. I also believe there is speculation that Pluto might be the moon of another possible planet.

Also, I have read that there have been other speculations regarding a tenth planet, that was located closer to the sun. It's like, in between the Earth and Mars, but way off in the distance...if that makes any sense. I remember reading that somewhere.

 

1. planets aren't all solid (see jupiter, saturn, neptune, uranus, you know the big gas giants that orbit)

as for size when do you decide when something fits into a category based on that, there are enourmous asteroids in the belt, some bigger than some moons, and mars moons are something like 9 and 25 miles across, nomenclature is b.s. and really a lot of your distinctions can be totally eaten by the facts of our own system, let alone others

 

Nomenclature is important, it is how we communicate with others. Sometimes it needs to change or be refined in order to be useful. That is why astrologers call the moon and sun "planets", but astronomers don't. Astronomy developed to the point that "moving against the fixed stars" was an insufficiant definition of "planet."

Unconnected to the preceeding, the new planet's(?) orbit is highly inclined to the plane of the ecliptic and highly eccentric. Much more so than Pluto.

Interesting factoid, in its path around the sun, the Moon's path is always concave towards the sun.

I've heard that, but I doubt its going to happen.
