On March 21, 2022, the number of known exoplanets passed 5,000 according to the NASA Exoplanet Archive. The music is created by playing a note for each newly discovered world. The pitch of the note indicates the relative orbital period of the planet. Planets that take a longer time to orbit their stars are heard as lower notes, while planets that orbit more quickly are heard as higher notes.
