Don’t call it Planet Nine. 


That nickname for the big world that may lurk unseen in the far outer solar system doesn’t show the proper amount of respect to the discoverer of the original ninth planet, Pluto, a group of researchers argues in a new message to their colleagues.  


The International Astronomical Union (IAU) famously reclassified Pluto as a “dwarf planet” in 2006. That decision remains highly controversial today, as made clear by the new note, which appeared in the July 29 issue of the Planetary Exploration Newsletter.


The message, titled “On the Insensitive Use of the Term ‘Planet 9’ for Objects Beyond Pluto,” reads:


“We the undersigned wish to remind our colleagues that the IAU planet definition adopted in 2006 has been controversial and is far from universally accepted. Given this, and given the incredible accomplishment of the discovery of Pluto, the harbinger of the solar system’s third zone — the Kuiper Belt — by planetary astronomer Clyde W. Tombaugh in 1930, we the undersigned believe the use of the term ‘Planet 9’ for objects beyond Pluto is insensitive to Professor Tombaugh’s legacy.

“We further believe the use of this term should be discontinued in favor of culturally and taxonomically neutral terms for such planets, such as Planet X, Planet Next or Giant Planet Five.”


Nearly three dozen researchers signed onto this message. They are:
