The first of these planetary rings was detected in 1968 by a team led by Edward Guinan. [168] The proposed New Horizons 2 mission (which was later scrapped) might also have done a close flyby of the Neptunian system. An alternative concept is that they formed closer to the Sun, where the matter density was higher, and then subsequently migrated to their current orbits after the removal of the gaseous protoplanetary disc. New York, Neptune's distance from the Sun. Eighth planet in distance from the Sun (7) Crossword Clue [147] The existence of arcs was difficult to explain because the laws of motion would predict that arcs would spread out into a uniform ring over short timescales.
