Humanity Star was a reflective passive satellite designed to produce visible, pulsing flares. The satellite was launched into orbit by an Electron rocket on 21 January 2018 and entered into the atmosphere on 22 March 2018. The reaction to Humanity Star was mostly negative by astronomers, as it interfered with their observations.
