We studied the dynamic evolution for pairs of trans-Neptunian objects in close orbits with semi-major axes of more than30 au. Early have been found 26 pairs of trans-Neptunian objects. All pairs belong to cold Classical Kuiper belt objects.The dynamic evolution of pairs of trans-Neptunian objects in the past 10 Myr has been studied numerically based onnominal orbits. We searched for low relative-velocity close encounters between trans-Neptunian objects in pairs as well asthe minima of the Kholshevnikov metrics and the convergence of the lines of nodes and apses to estimate the age of thepairs.
