Some Captivating 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’ll go over some of the intriguing facts about Neptune.
The astronomers from early times detected 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. Therefore, when they saw Neptune, the astronomers did not observe the disc shape of the planet.
The astronomers and researchers discovered this planet through mathematical calculations. 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, in September 23, 1846, Johann C Galle discovered Neptune. This discovery was also attributed to the French and British astronomers as their calculations were instrumental its discovery.
Because of its blue appearance, Neptune was named after the Roman god of the sea. Its naming is similar to the rest of the planets of the solar system that are 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 consists of eighty percent hydrogen, 19% of helium and one percent of water, ammonia and methane.
The blue color which characterizes this planet is due to the presence of methane in its atmosphere. 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’s quite possible that you will find far more moons that are yet to be found.
The first spaceship to reach Neptune was called the Voyager 2, 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; Galle, LeVerrier, Adams, Lassel, 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.
