A number of ESO’s telescopes at La Silla and Paranal, Chile, were used to observe the dwarf planet Makemake. Mainly, these are the Very Large Telescope (VLT), New Technology Telescope (NTT) and TRAPPIST (transiting Planets and PlanetesImals Small Telescope) telescopes. The data obtained with other smaller telescopes in South America such as the one in Cerro Armazones, the place where the European Extremely Large Telescope (E-ELT) will be built, were combined with the main ones to obtain the maximum amount of information.
