Dwarf Planet Pluto Orbit Diagram
This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Dwarf Planet Pluto with respect of the Sun and the orbits of the major planets. The position of Dwarf Planet Pluto and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!

Distance of Dwarf Planet Pluto from Earth
The following chart shows the distance of Dwarf Planet Pluto from Earth as a function of time. Distance data is measured in Astronomical Units and sampled with a 2 days interval. The reported distances might be inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of Pluto is also available as a real time updated value in the Live Position and Data Tracker.
Light Curve of Dwarf Planet Pluto
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.
