Trillions (maybe even way beyond septillions) of planets around our Sun. Your definition has no lower size limit. Do you count a single Iron ion orbiting the Sun in between Jupiter and Saturn a planet? How about a dust grain composed of between a hundred and a thousand atoms? How about a five micron chip from an asteroid released by a collision?
If you choose this idea for a planet, you are changing the definition of the term very substantially.
