Mercury

Introduction of the latest news: As the belt of the middle-aged sofa potato, the orbit of our solar system's planet is also expanding. This happens because our stars become older and the gravity of the sun gradually decreases as the quality is lost. Recently, the NASA and MIT scientific team indirectly measured solar mass loss and other solar parameters by observing Mercury's orbit changes.

The smallest planet in the solar system, closest to the sun, is only slightly larger than the moon on the earth. From the surface of Mercury, the amount of sun is more than three times that of the Earth and the brightness of the sun is 11 times higher.

Although close to the sun, Mercury is not the hottest planet in our solar system - the planet belongs to the nearby Venus - but it is the fastest orbiting sun every 88 earth days. Explore Mercury>

Due to Mercury's elliptical elliptical orbit and slow rotation, the morning sun rises temporarily, seems to rise again and rise again from some part of the surface of the planet. The same happens in reverse at sunset

The smallest planet in our solar system plays an important role in our collective imagination. Many science fiction writers including Isaac Asimov, C · S · Lewis, Ray Bradbury, Arthur C. Clark, H · P · Love Craft are inspired by Mercury. Television and filmmakers have also discovered that this planet is the ideal place to tell the story. In the invader gym of an animated television program, Mercury's extinct Martian became a prototype huge spaceship. In the 2007 movie "Sunshine", the Ikaros 2 spacecraft entered Mercury's orbit and met Icarus.

In Calvin 's and Hobbs' cartoons, Calvin and his classmate Susie made a speech about Mercury. Among them, Calvin's contribution was full of suspicious information: "Mercury was named after the Roman god with wings." Calvin said. "Mercury is the god of flowers and bouquets, that is why he is a registered trademark of FTD Flow List today, why would they name the planet for this person, I can not imagine."

What is mercury? Mercury (Hg) is a heavy metal that you can find in the Earth's crust. It is released into the environment and has natural phenomena like volcanic eruption. Mercury usually exists in three forms: elemental, inorganic, organic. In nature, mercury is mainly contained in compounds and inorganic salts. It is rare that it is a liquid metal. Human activities such as coal and gold mining are now the main cause of mercury release into our environment. Metal or elemental mercury (odorless, shiny, silver-white liquid) is commonly used in thermometers, barometers, and fluorescent lamps. Mercury thermometers gradually withdraw from most hospitals and other clinical facilities due to concerns about the toxicity of mercury. Mercury inhalation by exposure to water soluble mercury (eg methylmercury), inhalation of mercury vapor, or ingestion of all forms of mercury

Mercury thermometers and mercury bulbs are not as common as they were before. When handled carefully, the amount of mercury contained in them is unlikely to be a health problem. However, since mercury is difficult to collect and it is easy to erroneously cause greater exposure problems, broken items still need to be cleaned carefully. If possible, powdered sulfur can be applied to the spill to produce a solid compound that is prone to be removed from the surface rather than liquid sulfur. Chelate therapy for acute inorganic mercury poisoning can be performed using DMSA, 2,3-dimercapto-1-propanesulfonic acid (DMPS), D-penicillamine (DPCN) or dimercaptopropanol (BAL). Only DMSA is approved by the FDA for treatment of child mercury poisoning. However, some studies have found that DMSA treatment does not produce significant clinical benefit to mercury vapor induced intoxication.
