How bright is Dwarf Planet Pluto?
The current visual magnitude of Dwarf Planet Pluto is 14.42. Given its brightness, Dwarf Planet Pluto should be visible with the help of a telescope havng an aperture of 8 inches (200mm) or more.
The following chart is the predicted light curve (visual magnitude as a function of time) of Dwarf Planet Pluto, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
