Neptune Planet, Orbit, Satellites, Ring
Neptune planet, Neptune's orbit, Neptune's moons and what to know about Neptune ring Neptune planetIs the eighth planet in the Solar System. It was first discovered by Galileo Galilei. However, it was thought to be a star due to the inability to understand the speed of movement. Its discovery was made as a result of mathematical calculations. It began to be sought after the French astronomer Urbain Le Verrier and British astronomer John Adams realized the unusual changes in the orbit of Uranus and created the thesis that another planet must exist in the region where the change occurred. And on September 23, 1846, German astronomer Johann Galle detected Neptune through a telescope. Its name today comes from ancient Roman and Greek gods like all other planets. Neptune is the ancient Roman sea god. The equivalent in Greek mythology is Poseidon. Physical Properties of Neptune Neptune's cloud cover has a vibrant blue hue as a result of the absorption of red light from methane gas, especially in planets with a hydrogen-helium atmosphere, originating from an unidentified compound. Photos of Neptune show us a blue planet. Under its atmosphere, water is often referred to as an ice giant, since traces of ammonia and methane have a dense, aqueous fluid mixture and have about 17 times the Earth's mass and about 58 times its volume. NASA thinks Neptune's rock core is almost equal to Earth's mass. Another interesting feature of Neptune is that the winds formed on it can reach a speed of 2400 kilometers / hour. With this feature, it has the fastest winds in the Solar System. These winds were observed in a large dark storm that occurred in Voyager 2 's southern hemisphere of Neptune in 1989. This oval-shaped counter-clockwise "Large Dark Stain" was large enough to contain the whole Earth and was moving westward at a speed of about 1200 kilometers / hour. This storm seemed to have disappeared later on with the Hubble Space Telescope. Hubble has announced the appearance and subsequent disappearance of two Large Dark Spots over the past decade. Neptune's magnetic poles are inclined about 47 degrees compared to the poles around which it rotates. Therefore, the Earth's magnetic field, which is about 27 times stronger, undergoes a highly effective oscillation during each rotation. Scientists also calculated that one day of the planet Neptune remained under 16 hours by examining the cloud formations above the gas giant Neptune. Orbital Properties of Neptune The Neptune planet holds the elliptical, oval-shaped orbit planet at an average distance of about 4.5 billion kilometers from the Sun, or about 30 times more than Earth. Thus, Neptune makes the planet invisible to the naked eye. Neptune completes its orbit around the Sun in about 165 Earth years and completed its first orbit in 2011 since it was discovered. Pluto moves in the orbit of Neptune every 248 years, for about 20 years, and during this time Pluto is closer to the Sun than Neptune to the sun. However, Pluto is the most distant planet from the Sun, since it was included in the dwarf planet class by the astronomy board in 2006. Average distance of the orbit to the Sun : 4,498,252,900 km. 30,069 times further from Earth.
Perihelion (The closest distance of the orbit to the Sun) : 4,459,630,000 km. It is 29.820 times further from Earth. Solar (Orbital's farthest distance from the Sun) : 4,536,870,000 km. It is 30,326 times further from Earth.
Neptune has 14 moons with names from Greek mythology. The largest ever, Triton, named after Lassell, was discovered by amateur astronomer William Lassell on October 10, 1846. TritonIs Neptune's only spherical satellite. The 13 other satellites of the planet have no regular shape. In addition, Triton is the only satellite that reverses its planet among large satellites. Since large satellites are generally thought to have formed during the formation of the planet, it is expected to rotate in the same direction as the planet. Small satellites may have become the gravity of the planet later. So they can turn in different directions. It is believed that Triton might have been a dwarf planet that he captured later rather than breaking off the planet Neptune. According to NASA. Neptune's gravity brings Triton closer to the planet; this means that after millions of years, Triton will be close enough to break up under the influence of the force of gravity.
The surface temperature of Triton can reach minus 235 degrees and with this feature it is known as one of the coldest places of the solar system. However, Voyager 2 has discovered geysers that erupt ice-cold items with warm interiors from up to 8 kilometers. Scientists are exploring the possibility of an underground ocean on an ice-covered satellite. It was also discovered that seasons exist in Triton in 2010.

Working with SETI in 2013, scientists captured Neptune 's "lost" satellite called Naiad using data from the Hubble Space Telescope. Since Voyager 2 discovered this satellite in 1989, this 100 kilometer wide satellite has not been seen. Also, Hubble Space Telescope in 201314th satellite called " S / 2004 N 1 " was found. Neptune's smallest satellite was only 18 kilometers wide. This satellite was given a temporary name. Because it is the first satellite to be discovered from the images taken in 2004. Neptune's Rings Neptune's rings are not uniform. They consist of large rock clusters in the form of bows. The rings are thought to be relatively young and short-lived than the rings of other planets. According to the results of the observations announced in 2005, Neptune rings were realized to be much more unstable than previously thought. Even some of the available public resources in support that all the time spent away from the planet .
