Trans‐Neptunian objects (TNOs) represent a population of bodies that never approached the Sun and preserved information on the conditions in the primordial planetary nebula. Unfortunately, little is still known about their physical properties. Low resolution spectroscopy of TNOs can change this but it requires the largest, 8 – 10 m class telescopes to be used.
