    I mean, you can choose to define things however you want for your personal headcanon.

    But for communication to work, people need to agree upon meanings. Iā€™m guessing you donā€™t have a PhD in astrophysics, so your opinions are very unlikely to sway the consensus opinion on how these things are defined. And itā€™s their definitions that most lay people are going to take our cues from.

    But even from the perspective of trying to come up with your own definitionsā€¦itā€™s rather poor practice to define things by presupposing your desired outcome. They didnā€™t define a planet vs dwarf planet by reference to Pluto, even though their desired goal was to exclude Pluto. They found actual criteria and used those. The definitions youā€™re giving, by stating ā€œstellar class with Saturn at the boundaryā€ does not work as a very good definition. Though again, youā€™re free to use that for yourself if you wantā€¦so long as you understand you will have severe difficulty communicating with others.

      Iā€™m guessing you donā€™t have a PhD in astrophysics,

      Most of the thesis is written, and the definitions I am giving are common among my colleagues. This is the growing consensus post-Cassini/Juno.

      Iā€™m not choosing these definitions with any presuppositions. Iā€™m using Saturn as a useful marker of the boundary because of its hybrid internal structure as revealed by kronoseismology.
