![]() ![]() planetary spacecraft Voyager 2 was the first human spacecraft to visit Neptune. The distance between Earth and Neptune changes constantly, but the closest Neptune gets to us is 4.3 billion km. It completes an orbit of the sun once every 165 years. Neptune is the farthest planet from Earth When Pluto lost its classification as a planet in 2006, Neptune became the farthest planet from the Earth and the sun. It has eight known moons, of which Triton is the largest, and a ring system containing three bright and two dim rings. Its small, rocky core is surrounded by a hot, dense fluid of water, methane and ammonia. The blue gas giant, which has a diameter four times that of Earth, was named for the Roman god of the sea. Neptune, the farthest planet from the sun, was discovered in 1846. Noting its movement relative to background stars over 24 hours confirmed that it was a planet. That had never before been seen for this planet or for any other planet of its class, so JWST is really delivering on its promise. Neptune has a diameter of 34,503 miles (55,528). On September 23, 1846, Le Verrier informed Galle of his findings, and the same night Galle and his assistant Heinrich Louis d’Arrest identified Neptune at their observatory in Berlin. Neptune is the fourth largest planet in our Solar System and it is the smallest of the giant gas planets. 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. The cold, blue planet is about 30 times farther away from the sun than Earth and takes around 165. German astronomer Johann Gottfried Galle discovers the planet Neptune at the Berlin Observatory. Neptune is the farthest planet from the sun and one of two 'ice giants' in our solar system. ![]()
