Pluto can again become a planet

Reason pluto lost its statusthe planet, is invalid, according to a new study from the University of Central Florida at Orlando. In 2006, the International Astronomical Union, a group of world experts in astronomy, established the definition of a planet according to which it must “clear” its orbit or, in other words, have the greatest gravitational force in its orbit.

Since Neptune's gravity affects the nearbythe planet Pluto, and Pluto shares its orbit with the ice objects of the Kuiper belt, the status of the planet Pluto was deprived. However, in a new study published in the journal Icarus, planetary scientist Philip Metzger reported that this standard for classifying planets is not supported by research literature.

Why is Pluto not a planet?

Metzger revised the scientific literature forthe last 200 years and found only one publication - from 1802 - that uses the argument of clearing the orbit to classify the planet, based on the arguments already refuted.

He says that satellites such as Titan and Europe have been considered planets since the time of Galileo.

"By definition, the MAS fundamental objectplanetary science, the planet, is determined on the basis of a concept that no one uses in their research, ”says Metzger. “And deprives this status of the second in complexity, the most interesting planet of our solar system. We have a list of more than a hundred recent examples where planetologists used the word “planet” in violation of the definition of the MAS, but did so because it was functionally useful. The MAC definition is sloppy. It does not explain what it means to clear your orbit. If we take it literally, there are no planets, because no planet clears its orbit ”.
