The relativistic Doppler shifting of visible electromagnetic radiation tobeyond the human ocular range reduces the incident radiance of the source.Consequently, luminous astrophysical bodies (LABs) can be rendered invisiblewith sufficient relativistic motion. This paper determines the proper distanceas a function of relativistic velocity at which a luminous object attainsocular invisibility.
