Some Fascinating 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 near 49,500 km in diameter, and so it’s nearly four times the size of the Earth. The distance between the Earth and Neptune is about 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 will discuss a few of the interesting facts about Neptune.
Neptune was observed by the astronomers from ancient times including Galileo. Nonetheless, Galileo didn’t comprehend he was seeing a planet. In early times, we didn’t have telescopes that were sufficiently powerful to assist the astronomers and researchers identify planets. Therefore, when they saw Neptune, the astronomers did not observe the disc shape of the planet.
Mathematical calculations were used by the astronomers and researchers to find this planet. In 1843, a British astronomer and mathematician in was instrumental in determining 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.
Because of its blue appearance, Neptune was named after the Roman god of the sea. Its naming follows the rest of the planets of the solar system which are all named after Roman gods.
This planet consists of iron, iron and other silicates. The Mantle of Neptune chiefly includes methane, ammonia, water and other chemical substances. Neptune’s mantle is quite hot with temperatures that range from 3000 to 5000K. The atmosphere includes 80% hydrogen, 19 percent of helium and 1 percent of ammonia, water and methane.
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.
Astronomers and researchers have found thirteen moons that revolve around Neptune till today. It’s quite possible that you will find far more moons that are yet to be found.
The Voyager 2 was the first spaceship to reach Neptune, and it did so in 1989. It took images of the planet which helped the researchers in discovering that the planet has five rings. These rings are; LeVerrier, Galle, Lassel, Adams, and Arago. People today believe these rings formed one planet when one of those moons of Neptune got near and broke into countless particles because of the gravity at Neptune.
