Alastair Cameron was one of the first to postulate the existence of this region, and a notable object here was discovered by Charles Kowal. Emission spectra of objects here have strong methane peaks, and objects not found at its edges are termed (*) "cubewanos". Chiron, Pholus, and other objects known as the "centaurs" are believed to originate in this region. Objects in this region include Haumea, Varuna, Sedna, and an object formerly known as Xena, now called Eris, whose discovery sparked some of the objects in this region to be re-classified as dwarf planets. For ten points, name this region of icy objects beyond the orbit of Neptune, named for Edgeworth and a Dut
