It’s positioned between Uranus and Pluto, and is sometimes referred to as the Blue Giant. The planet is almost 49,500 km in diameter, which makes it almost 4 times the size of the planet, Earth. Also, Neptune is located around 4.4 billion km from Earth, and for that reason, it’s not visible to naked eyes. Even using binoculars, you won’t have the ability to observe the planet clearly.
Here are some fascinating facts about Neptune:
• Neptune was observed by several astronomers from early times. The great Galileo observed Neptune, but didn’t realize he was looking at a world. In early times, the telescopes weren’t potent enough to assist the researchers and astronomers discern planets. When Neptune was seen, the astronomers couldn’t find the disc shape of Earth.
• The world was detected through mathematical calculations. In accordance with the calculations, it was estimated that Neptune was one billion kilometers farther from Sun compared to Uranus.
He also has the exact results as the British astronomer.
• The discovery of Neptune is credited to the British astronomer in addition to the French astronomer.
• The heart of the planet contains nickel, iron and other silicates. While the mantle of Neptune is composed of water, methane, ammonia and other chemical compounds. The mantle of Earth is
• The atmosphere of Neptune is composed of 80 percent hydrogen, 19 percent helium, and one percent of ammonia, water and methane.
• The world gets its characteristic blue colour because methane within its atmosphere absorbs the red light in sunlight and then reflects it blue into space.
• Until today, researchers and astronomers have found thirteen moons revolving around Neptune. It’s quite possible that there are still more moons waiting to be found.
• Voyager 2 was the first spaceship to reach Neptune from the year 1989. It took pictures of the world and through these images, researchers discovered that the world has five rings. These rings are known as Galle, LeVerrier, Lassell, Arago and Adams. It’s thought that the rings formed when one of world’s moons got too close and broke up into countless particles as a consequence of Neptune’s gravity.
