In a paper published in the scientific journal Icarus researchers argued that the IAU should change their position on Pluto.
They said: “The IAU should rescind their non-scientific definition and stop teaching the revisionist history.”
For an astronomical body to be considered a planet it needs to be spherical, orbit a star and not share gravitational space with other objects in its orbit.
The IAU’ 2006 reclassification was based upon the presence of objects known as ‘plutinos’ within its orbit.
However, the researchers from universities, observatories and research institutes are critical of that decision.
In a five year study of astronomical and planetary literature on the subject they argue that the IAU decision was “rushed”.
They also go on to claim that the classification was unscientific and based on a “folk concept of planet that contradicted the scientific view”.
Pluto’s planetary status has provoked considerable debate in the astronomical community since 2006.
