The Coleta de Dados Colles are a cluster of hills ("colles") on the smooth plains of Sputnik Planitia on Pluto.^[1] They actually represent blocks of water ice floating in the denser nitrogen ice of the Planitia. The hills were informally named on July 28, 2015, by the research team of the New Horizons mission after the first Brazilian satellite, the Satélite de Coleta de Dados ("Satellite for Data Collecting" in Portuguese). The ridge's name means "Data Collecting Colles" and has yet to be recognized by the IAU.
