5th-7th Age project

Very rough approximation of the interpretaton over 2,5 years ago. This is not a map of Middle Earth. Nor is it a map of Europe. "April fools", says the nick Laichalaf.

comets faraway

The simplest possible diagram of orbital alignement (degrees) of comets between 200-2000 AU (average), just because en.wikipedia was missing this. There's likely some observational bias here, as I believe the comets are easiest to find near the celestial north pole. It's pretty easy to point a wide-field telescope towards Stella Polaris, and take an overnight shot or several. Comets would show as ripples or lines curving out or in between the regular arcs of normal stars.
