Herschel Space Observatory observed 130 trans-Neptunian objects (TNO) and
Centaurs within the open time key program "TNOs are are Cool".
The goal of this program is to determine sizes and albedos as well as to constrain
thermal properties. I present results and sample analysis, concentrating
on the most numerous dynamical class of TNOs, the classical Kuiper belt objects.
