The planet Neptune is eight planets from the Sun and is the fourth largest planet, approximately 17 times larger than Earth. It is also one of the slower planets, taking only 165 years to orbit the Sun. It has a diameter of 49,532 km, an orbit of 4,504,000,000 km from the Sun, and a mass of 1.0247e26 kg. it rotates about once every hour and 7 minutes. The planet cannot be seen without a telescope. The god of the sea was called Neptune by the Roman name. The Greek god of the sea is Neptune.
By Galileo Galilei in 1613. It was discovered by an Italian scientist in 1613. Observing only two continuous nights, he could not clearly understand the motion of the planet to make the star so wrong. In 1846, his identity was revealed. It was discovered that the planet that astronomers thought about Uranus did not behave according to Newton’s “laws of motion”. working independently, Urban J.J. Leverrier and John Couch Adams calculations confirmed by director Johann G. Galle together with his assistant Henry L. D’Arrest of Urania Observatory. With this discovery, the French and the English sought credit and rights to give the name of the newly discovered planet. Today both countries are credited with the discovery of Neptune.
The planet is composed of hydrogen, helium, water and silicates. Silicates are rock-like minerals in the Earth’s crust, but Neptune does not have a solid surface. The clouds that surround the planet are dense and move at speeds of up to 700 miles per hour. The last surface consists of frozen methane. The darker clouds below the methane clouds include hydrogen sulfide. The blue color of the planet is largely the result of the red light red found in methane. atmosphere
The planet was visited on August 25, 1989 by only one spacecraft, Voyager 2. The spacecraft found a dark section that looked like a “storm” consisting of a mass of gas. It was called “The Great Spot . However, it disappeared by the Hubble Space Telescope in 1994. It was thought to have either dissipated or just been cloaked by the atmosphere.
With 13 known moons, seven are named and Triton is the largest with a diameter of 2,705 kilometers and a distance of 354,760 kilometers from Neptune. It is the only known satellite with a retrograde orbit and travels once around the planet every six days. the other seven moons are Naiades, Thalassa, Despina, Galatea, Larissa, Proteus, and Nareid. Apart from Triton, which was discovered by William Lassell and Nereid by Gerard Kupier, the rest of the moons were discovered by Voyager 2.
Neptune has four rings. Three distinct and one faint ring. Compared to the rings of Saturn, these circles are much darker and fainter. The rings consist of dust particles and are unevenly spread. The outermost ring is 63,000 kilometers from the planet, also known as the main or Adams ring. The remaining three are Plateau or Lassell, Arago, Inner or LeVerrier and Diffuse or Galle.
