| The term planet means something like wanderer, and in ancient times all the objects were so called, who are wandering across the sky.
So I think only the planets that were known in ancient times, should be called planets: Sun, Moon, Mars, Mercury, Jupiter, Venus!
All other would then be 'dwarf planets' because they are so small that they can not seen! 
Don't forget to look here.

| JackDole wins. An awards ceremony will be held in the Defining Planethood Thread. Planet-themed cakes will be served along with posters of dissenting opinions.
(No, seriously, use that thread if you're still going to discuss how to define a planet.)

| Scientists have just discovered that Pluto has a subsurface ocean, http://gizmodo.com/it-look....2418191
Pluto is stranger and weirder than most have thought.

| nothing from nasa etc
liquid? by how?
the other moons in the solar system have subsurface liquid oceans because of the strong tidal forces between them and thier parents (jupiter, saturn) but pluto? not only its more far from the sun but has no strong tidal forces.
but maybe it is possible. and someone will correct me

| Well they said that the surface of Pluto is newer and is smooth, could only be icy volcanoes or an ocean.

| I believe they noted the heat may be generated by radioactive decay of elements in Pluto's core. Speculative, but possible.

| Pluto is like every other icy planet. The heat and pressure of being further down into the planet melts the ice. Seen in Titan, Europa, Enceladus, etc.

| steeljaw354, a thread for discussing Pluto already exists. A new thread was unnecessary.

It is very possible to have the ocean in between the crust and core, suspending the core in an ocean and having it attached to the surface by rock formations. Maybe life?

| well in the other bodies you said horn, they can support liquid water oceans because of the tidal forces with jupiter and saturn.
but pluto dont get such strong forces and is also colder. i dont think water ocean can be there. but maybe some other liquid

| Quote steeljaw354 (  ) Well pluto has a big moon.
its not that big. but compare to pluto it is big. i really dont know if possible but i think the tidal forces between pluto and charon isnt high enough to form great big heat inside pluto. if there is heat inside pluto that can form water ocean.
its probably because of radioactive decay inside pluto core

| Who said it has to be water? Maybe it is liquid nitrogen or ammonia.

And who said it can't be liquid helium, with that logic?
