Uranus is a blue gas planet. This color is because Uranus's atmosphere is rich in methane. The red and orange light in the sun reflected from the atmosphere is absorbed by methane. Only the blue and green light is transmitted out, which shows a unique color. Neptune is also blue for this reason.
Uranus' orbit is also very strange. He is like a naughty child, lying on his orbit and rolling. Scientists speculate that Uranus has been "harmed" by many asteroids, causing his orbit to be discovered and changed, forming this "lying down and rolling" look. It takes 84 years for him to revolve around.
Why is Uranus scary? Because it is the coldest planet in the solar system, even though Neptune is farther from the sun than him. How cold is he? The surface temperature is: -197.2 degrees Celsius. Our fragile body, like humans, freezes to death within 1 second on its surface.
Uranus was discovered by musician William Herschel. Herschel loved music since she was a child and showed her talent in this area very early. He learned to play the violin with his father at the age of 4, and later learned to play the oboe, and soon became an excellent oboe player. Due to difficulties in family background, he left school at the age of 16 and joined the Imperial Guards Band like his father, where he worked as a violin and oboe player, making a living on music. In addition to being a music lover, Herschel also likes astronomy, likes to polish mirrors to build telescopes, and create reflective telescopes with a maximum diameter of 1.22 meters at that time. It is said that he made some money by selling telescopes.
1781 On March 17, he used his own telescope to discover a new star. He claimed that he had discovered a comet, but the comet had no coma or tail; on April 23, he informed the royal astronomer Muskillin of his discovery. In 1783, French scientist Laplace confirmed that Herschel was discovering a planet. In recognition of his achievements, George III gave Herschel an annual allowance of £200, on the condition that he had to move to Windsor so that royal officers could observe through his telescope. In this way, he started astronomical observation full-time, and even brought her sister to observe together without regard for her.
Finally, he became the founder of stellar astronomy and was known as the father of stellar astronomy. The first president of the Royal Astronomical Society of England. Academician of the French Academy of Sciences. Use a large reflective telescope designed by himself to discover Uranus and its two satellites, Saturn's two satellites, the space movement of the sun, and infrared radiation in the sun's light; compile the first binary and star-gathering table, publish the star cluster and nebula table; and also study the structure of the Milky Way.
