1. Officially the outermost major planet in the solar system after the demotion of
Pluto to dwarf planet status in 2006. An ice giant with a cool, deep blue coloration. Similar composition to Uranus.
Mean distance from the
Sun 2.798 billion miles. Equatorial diameter 30,775 miles, give or take 20. Polar diameter 30,250 miles, give or take 40. Visible cloud
deck is at temperatures around 218 degrees Centigrade below zero. Orbits once in 164.79
Earth years, or as of this writing just about once since it was discovered by Urbain
le Verrier and Johann Gottfried Galle in 1846. Visited by Voyager 2 in 1989. At last count had
13 recognised moons. Had a dark blue marking looking remarkably similar to Jupiter's Great
Red Spot, with Neptunian proportions and colour scheme, at the time of Voyager's flyby, which was promptly named the Great
Dark Spot; apparently this has since disappeared.
2. Roman divinity of the sea, influenced by but not identical to the Greek Poseidon. Also a god of horses. Had a fishy lower body and brandished a trident.
