How many planets are in the Solar System?

[IronWing]

Damn new astronomy.

Got kicked out by a bot detector for giving wrong answer. Poor Pluto. :'(

There is something profoundly and deeply wrong with being declared non-human by an algorithm.

Fuck that "planetlet" dwarf planet bullshit. Pluto has been a planet for most of my life...AFAIC, it's still a planet...just a small one.

 

[Danwar]

yeah a small planet which is actually smaller than our moon and over half of its mass its ice so that if it were closer to the sun it will melt away and create a tail

doesnt sound like a planet to me

Our moon is pretty big and Jupiter is a ball of gas. I don't see the issue.

I don't think the definition of a planet matters. At the specific level we commonly think of, all we need to know is whether something orbits the sun and not something orbiting something orbiting the sun.

Then we can pair it up with the earth. The moon wouldn't meet this definition.

If .99999999=1 then Pluto is a planet.

The problem with designating Pluto as a real planet is that you have to add a few more, like Eris and Ceres. It makes a lot more sense to just remove Pluto.

Pluto is where the aliens have their secret base. The next step in their plan is to wipe all knowledge of Pluto from our data files.

This probably gives away my age but...

... guess what, there are five oceans in the world. (ignoring the world ocean thing)

If Pluto is a planet then so are Ceres (in the asteroid belt), Pluto, Haumea, Makemake, Eris, 2007 OR10, Sedna, Quaoar, Orcus, and probably many other undiscovered "dwarf planets".

Personally, I'd define a planet as an object big enough to retain an atmosphere, but not so big it starts nuclear fusion in its core. Which would rule out Mercury as well. :sneaky:

Posted from the second planet in a system of seven.

And yet there are seven seas.

Won't Mercury hold an atmosphere if it wasn't so close to the sun?

If pluto is a planet then there's about 30 planets known in the solar system.

In 2036 Apophis is going to kill us all.

Damn whippersnappers! Why - back in my day we had 9 planets!

Not to mention the whole 'how many continents' thing

Just as God intended.

The problem is that Pluto is tiny. We have much better technology today and are finding lots and lots of objects in our solar system. Pluto isn't that special anymore.

Damn antiplutist.

 

[SlitheryDee]

I still think of Pluto as a planet, therefor it is a planet. Besides, how can something that iOS auto capitalizes not be the real deal?

 

[ImpulsE69]

On Jupiter, Earth isn't considered a planet.

 

[bigrash]

There are 9 planets. Pluto is still a planet to me.

Don't worry
