@LouisIngenthron yup, i mean the one that includes the moon as a planet, a secondary planet.

@LouisIngenthron People do tend to assume, improperly, that planet means "major planet". But that seems silly to me.

I was fine with the old definition really.

Everything is a planet, you just have primary and secondary planets depending if its a primary or not.

@LouisIngenthron I never said what type of planet pluto is. Pluto is a planet. There are several types: Major, minor, dwarf, etc.. those are categories of planets

My definition? What my definition. I use the official definition of a planet. It must be in orbit around its star, not a star, large enough to be nearly-spherical. These are just the standard definition for a planet.

A "Major Planet" is a class of planets that have the added criteria of clearing their path around the star with no similar sized or larger objects within itspath. But not being a major planet is not the same as saying something isnt a planet.

@LouisIngenthron ORbiting a star isnt enough, there are specific criteria.

@LouisIngenthron No, it doesnt orbit itself, also its a star (as sufficient mass to have fusion.

@LouisIngenthron I dont make the rules. Haumea is considered a planet by scientists so they must feel it is sufficiently round.

the sun doesnt orbit itself, so its not a planet.

The proper name for a "planet" without a star is a "isolated planetary-mass object" .. it is not a planet no.

@LouisIngenthron It would have to have a nearly round shape, orbit the sun. smaller objects arent usually nearly round, so usually not.

@cobratbq I mean it literally and scientists agree :)

@LouisIngenthron Haumea yes, Titan no according to current defitions, yes historically. Historically moons were called secondary planets.

@LouisIngenthron Sure is
