IAU Naming Procedures
See also: IAU definition of planetIn 2008 IAU modified its naming procedures such that objects considered most likely to be dwarf planets receive differing treatment than others. Objects that have an absolute magnitude (H) less than +1 (and hence a mathematically-delimited minimum diameter of 838 km) are overseen by two naming committees, the one for minor planets and the one for planets. Once named, the objects are declared to be dwarf planets by the IAU. Makemake and Haumea are the only objects to have proceeded through the naming process as presumed dwarf planets; currently there are no other bodies which meet this requirement. All other bodies are named by the minor-planet naming committee alone, and the IAU has not stated how or if they will be accepted as dwarf planets.

Famous quotes containing the words naming and/or procedures:
“Husband,
who am I to reject the naming of foods
in a time of famine?”
—Anne Sexton (1928–1974)
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
