Neptune, generally the eighth planet from the sun, was postulated by the French astronomer Urbain-Jean-Joseph Le Verrier, who calculated the approximate location of the planet by studying gravity-induced disturbances in the motions of Uranus. On September 23, 1846, Le Verrier informed Galle of his findings, and the same night Galle and his assistant Heinrich Louis dâ€ÖArrest identified Neptune at their observatory in Berlin. Noting its movement relative to background stars over 24 hours confirmed that it was a planet. The blue gas giant, which has a diameter four times that of Earth, was named for the Roman god of the sea. It has 14 known moons, of which Triton is the largest, and a ring system containing three bright and two dim rings. It completes an orbit of the sun once every 165 years. In 1989, the U.S. planetary spacecraft Voyager 2 was the first human spacecraft to visit Neptune. 73 de Scott KF5JRV Pmail: KF5JRV@KF5JRV.#NWAR.AR.USA.NA Email KF5JRV@gmail.com
