Abstract
We combine new measurements of the thermal emission from the Centaur 1997 CU26 with published optical photometry to determine the geometric albedo (0.045±0.010) and effective diameter (302±30 km). While these values are model dependent, they clearly show that 1997 CU26 is the largest of the known Centaurs and that its surface is very dark.Keywords
