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.
Neptune is visible in a good telescope.
Capitolus strode on board his ship and set sail across Neptune's kingdom.
