The term "dwarf planet" would have been available to describe all planets smaller than the eight "classical planets" in orbit around the Sun, though would not have been an official IAU classification. [18] The IAU did not make recommendations in the draft resolution on what separated a planet from a brown dwarf. [19]
It thus counts dwarf planets and planetary-mass moons as planets. Five bodies are currently recognized as or named as dwarf planets by the IAU: Ceres , Pluto (the dwarf planet with the largest known radius), [ 22 ] Eris (the dwarf planet with the largest known mass), [ 23 ] Haumea , and Makemake , though the last three have not actually been ...
The second resolution, 5B, defined dwarf planets as a subtype of planet, as Stern had originally intended, distinguished from the other eight that were to be called "classical planets". Under this arrangement, the twelve planets of the rejected proposal were to be preserved in a distinction between eight classical planets and four dwarf planets.
The term 'dwarf planet' arguably contains two words, a noun (planet) and an adjective (dwarf). Thus, the term could suggest that a dwarf planet is a type of planet, even though the IAU explicitly defines a dwarf planet as not so being. By this formulation therefore, 'dwarf planet' and 'minor planet' are best considered compound nouns.
Ceres, the largest object in the asteroid belt between Mars and Jupiter, is an "ocean world" with a big reservoir of salty water under its frigid surface, scientists said in findings that raise ...
The Dwarf Athletic Association of America and the Dwarf Sports Association UK provide opportunities for dwarfs to compete nationally and internationally in the Americas and Europe, respectively. The World Dwarf Games (WDG) are a multi-sport event for athletes of short stature. The WDG have been held every four years since 1993 and are the world ...
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
