  • "Objects near Plutinos that are not attracted into resonances with Neptune are called cubewanos. These make up the 'classical' Kuiper Belt, a relatively thin region of space that corresponds to the same plane in which most of the planets orbit, Parker explained.


    The first KBO found was initially designated 1992 QB1, Parker explains. Its a name that denotes the year, month and order of discovery and is typical for newfound objects whose orbits are not pinned down. It was later learned that 1992 QB1 was a 'main belt' KBO, not a Plutino, and so astronomers just began sounding out 'QB1' and a new term was born."
