They are found in a region sometimes named for Kenneth Edgeworth, and, unlike Plutinos, they do not have an orbital resonance with Neptune.
Types of these that range in temperature from 0.1 to 10 degrees Kelvin are known as "dynamically cold". The short period of 3.17 hours of one of these objects has led astronomers to speculate it has a highly elongated shape. Besides Varuna, solid ethane and methane have been found on one of these objects that once reached the unusally high temperature of negative 160 degrees Celsius named Quaoar. Strazzulla and Johnson argued that space-weathering was responsible for the redness in a cluster of these objects. David Jewitt and Jane Luu discovered the first of these objects in 1992 and named it Ouroboros. An object also classified as a dwarf planet, Makemake, is the largest one of these entities.
