For 10 points, name this area which lies beyond Neptune's orbit, and is named for a Dutch-American scientist.
Objects in this region with roughly circular orbits whose plane is approximately that of the ecliptic are called "cubewanos," and their distribution follows an inverse quartic relationship with distance. The area at the 1:2 orbital resonance is known as its namesake "cliff" and occurs at about 50 AU, while TL66 was the first "scattered" object found in it. It is the region where Varuna, Eris, and Charon are found, and it was thought to be the area where short-period comets originate.
