(voir plus loin pour la description en français)
The passage through the closest points between orbits (on the left).
Neptune (blue) catching up with Pluto (red) i.e. the actual closest approach between Pluto and Neptune on the right.
Orbits plotted in brighter colours above the ecliptic and darker below.
Major axis drawn showing perihelia (q) and aphelia (Q).
Colours and albedos illustrated
For the closest approach, sphere size is inversely proportional to the distance to facilitate correlation.
The dates and positions indicated.
Orientation
The Sun in the centre of the graph.
Yellow segment points toward the vernal point.
View from ~ 10 degrees above the ecliptic
