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!
