There are NO planets that don't orbit stars : once they don't orbit a star they don't follow the modern definition of a planet anymore
The modern definition of "planet" only includes things that orbit the sun.
Honestly, the IAU's definition of a planet is pretty useless.
We'll not have science in this discussion about science!
Rocky planets, gas giant planets, ice giant planets, dwarf planets, super Earth planets, hycean planets, lava planets, rogue planets...
