Why does a group of researchers want to reopen the debate on the definition of planets?

To the right, east of Sputnik, the plain is cut by what appear to be glaciers, the sunlight illuminating the area from behind highlights over a dozen layers of haze in the thin but inflated atmosphere. The photo was taken from a distance of about 18 thousand kilometers and the width of the photographed area is 1,250 kilometers. Credits: NASA/JHUAPL/SwRI

In the center of the image, to the left of Pluto's huge route that resembles a heart shape, lies the Tombo area (named after Pluto's discoverer). It is a vast craterless plain that appears to be at most a hundred million years old and may still be shaped by geological processes. This icy region north of Pluto's ice mountains has been named the Sputnik Plain in honor of the first artificial satellite. The surface appears divided into irregular shaped segments surrounded by narrow rings. In addition, there are groups of mounds and fields of small pits in this area. This image was taken by the LORRI camera on July 14 from a distance of 77,000 kilometers. Details smaller than a kilometer can be seen. Some of my areas look raw due to the image compression.
