The word planet comes from the Greek word πλανήτης (planetes) which is derived from the word
Two years ago the International Astronomical Union IAU elected to define the term planet, restricting it to the eight largest bodies orbiting the Sun, and deleting Pluto from the list.
But when the International Astronomical Union created its formal definition of the word planet in 2006 - and demoted Pluto by doing it - there was nothing in the fine print about how the object had formed.
Some planetary theorists argued that the term "planet" should only apply to the latter, even if two objects have exactly the same mass.
These worlds reflect visible light rather than shining in their own right in visible wavelengths, but why should we restrict the definition of the term planet to just those wavelengths that we can see?
Our word planet comes from a Greek verb meaning to wander.
Change how astronomers define the term planet, eh?
Similarly, our planet is our house, and we should maintain it with care, to ensure our happiness and the happiness of our children, of our friends, and of all the sentient beings who share this great dwelling place.
