Water-rich worlds (Europa, Titan, Enceladus, Pluto, Triton, etc) are ubiquitous in our solar system, and the building blocks of Uranus and Neptune are also supposed to be water rich (Mousis et al. 2018). The properties led astronomers to consider the possible existence of mass water-rich ...
"If the proposed Resolution is passed,the 12 planets in our Solar System will be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon and 2003 UB313. The name 2003 UB313 is provisional, as a "real" name has not yet been assigned to this object. " "T...
Disgruntled scientists renewed their vows this week to call Pluto a planet despite an international governing body's latest ruling to reclassify the tiny world. On Wednesday, the International Astronomical Union (IAU) declared that Pluto will henceforth be known as a "plutoid," a new class of ...
"Is Pluto a planet? Sure it is. But is it a major planet like Mars and Jupiter, or is that distant tiny body more in league with Ceres, long ago catalogued as the first and largest of the minor planets? What degree of 'planethood' should be conferred on an object orbiting a star...

For sure, physical properties of Pluto do not change if we call it a "planet", a "dwarf planet", a "candelabrum", or a "sea cow". Pluto stays the same Pluto regardless of all that. For physics or astronomy, naming does not really matter....
Alternative classification schemes continue to pop up. A 2017 proposal defined a planet as "a round object in space that's smaller than a star." This wouldmake Pluto a planet again, but it would do the same to theEarth's moonas well as many other moons in the solar system, and bring...
