 A small number of stars have proper names in pre-modern astronomical tradition, but most naked-eye stars are identified by their Bayer or Flamsteed designations.In modern astronomy, there has been a tradition of giving proper names to newly discovered heavenly bodies, initiated with the discovery of the planets beyond Saturn, and later extended to minor planets and moons.The naming of astronomical objects and surface features in those objects is handled by two bodies of the International Astronomical Union (IAU).
