Neptune is the eighth planet in our solar system. It is located between Uranus and Pluto, and is sometimes called the Blue Giant. Interesting fact - Neptune is almost 49, 500 kilometers in diameter, almost 4 times the size of our planet, Earth. In addition, Neptune is located approximately 4.4 billion kilometers from Earth and therefore cannot be seen with the naked eye. Even using binoculars, you will not be able to see the planet clearly.
Here are some interesting facts about Neptune:
• Neptune has been observed by many astronomers since ancient times. Even the great Galileo watched Neptune, but did not realize that he was looking at the planet. In ancient times, telescopes were not powerful enough to help researchers and astronomers distinguish planets.
• The planet was discovered through mathematical calculations in 1843. According to calculations, Neptune was thought to be one billion miles farther from the Sun than Uranus.
• Based on calculations by a French astronomer, Neptune was discovered by Johan C. Halle on September 23, 1846.
• Because Neptune looks blue, it was named after the Roman god of the sea, just like all other planets in our solar system are named after Roman gods.
• The core of the planet consists of iron, nickel and other metals in the composition of silicates. While Neptune's mantle is made up of water, methane, ammonia and other chemical compounds. Mantle of the planet
very hot with temperatures ranging from 3000 - 5000 degrees.
• The atmosphere of Neptune is composed of 80 percent hydrogen, 19 percent helium, and 1 percent ammonia, water and methane.
• The planet gets its characteristic blue color because the methane present in its atmosphere absorbs red light from the sun and then reflects it as blue into space.
• At the moment, researchers and astronomers have discovered thirteen moons orbiting Neptune, but there may be more.
• Challenger2 was the first spacecraft to reach Neptune in 1989. He photographed images of the planet and through these images, the researchers found that the planet has five rings. It is believed that the rings formed when one of the planet's moons got too close and shattered into millions of particles as a result of Neptune's gravity.
