A Few Fun Facts About Neptune
Neptune, sometimes referred to as the Blue Giant is the eight planet in the Solar System and its location is between Uranus and Pluto. Its diameter is close to 49,500 kilometers in diameter and thus it is almost four times the size of the Earth. The distance between Neptune and the Earth is nearly 4. 4 billion kilometers, and thus, you cannot see it with your naked eyes. Even in the event that you use the binoculars, you can’t see the planet nicely. Below we’ll go over some of the intriguing facts about Neptune.
The astronomers from ancient times observed Neptune including Galileo. Nonetheless, Galileo didn’t comprehend he was seeing a planet. In early times, there were no powerful telescopes to help the astronomers and researchers discern planets. Thus, when they discovered Neptune, the astronomers did not note the disk shape of the planet.
Mathematical calculations were used by the astronomers and researchers to find this planet. In 1843, an astronomer and mathematician in Britain was key in calculating the location of Neptune. Based on the calculations, the astronomer estimated that Neptune had been one billion kilometers farther away from the Sun compared to Uranus. Another French astronomer did the calculations and got similar results to the British astronomer. Using the calculations developed by the French Astronomer, Johann C. Galle discovered Neptune in September 23, 1846. This discovery was credited to the British and French astronomers since their calculations were key its discovery.
Neptune was named after the Roman god of the sea due to Its blue appearance. Its naming follows the remaining planets of the solar system that are named after Roman gods.
Iron, nickel and other silicates make up this planet. Methane, ammonia, water, and other chemical substances make up the mantle of Neptune. With temperatures that range from 3000 to 5000K, Neptune’s mantle is very hot. The atmosphere is made up of eighty percent hydrogen, 19% of helium and 1 percent of methane, water, and ammonia.
The presence of methane in the atmosphere results in the blue color which characterizes this planet. It absorbs the red light that comes from the sunlight then reflects it in the color blue in space.
Thirteen moons that revolve around Neptune till now have been discovered by astronomers and researchers. It is possible that there are more moons which are yet to be discovered.
The first spaceship to reach Neptune was called the Voyager 2, and it did so in 1989. It took pictures of the planet and using these pictures, researchers found that the planet has five rings. These rings are; LeVerrier, Galle, Lassel, Adams, and Arago. Folks believe that these rings formed a single planet after one of those Neptune moons got near and divided into countless particles as a result of the gravity in Neptune.
