Reply to comment by Mighty-Lobster in My (still kinda WIP) planet definition by Afraid_Success_4836

I dislike the term "planetary embryo" because it implies that the body is destined to accumulate additional material and "grow up" to be a rocky planet (or something larger). That's only one of several possibilities.

Yeah. I'm just summarizing the science. The OP (and you) are invited to come up with different words. The point is that there are roughly five types of bodies that orbit a star that themselves are not a star:

  • Bodies similar to asteroids, comets and KBOs
  • Bodies similar to Mars
  • Bodies similar to Earth and Venus
  • Bodies similar to Uranus and Neptune
  • Bodies similar to Jupiter and Saturn

The interested reader is welcome to assign them names if they wish.
