The Wonders and Mysteries of Sun Mercury Combinations ~ The planet Mercury is the closest to the sun and is now the smallest planet in our solar system. Mercury temperatures of 700 degrees Kelvin area on the side of the solar radiation to 90 degrees Kelvin above the night side. Mercury orbits the Sun once every 88 days and rotates on its axis every 58 days. Mercury's orbit is very elliptical and brings it as close to the sun than 46 million kilometers, as far away from the Sun than 70 million kilometers. We can observe Mercury Earth with telescopes, both visually and radio, but much of what we know about mercury, the result of three flybys by the 10 spacecraft in the 1970s Mariner 10 only photographed 40 to 45 Mariner executed percent of surface mercury and the rest was never seen up close. Have images from Mariner 10 reveled return a rocky surface similar to the Earths moon crater.
Mercury is about 4878 kilometers in diameter and this causes the mercury slightly smaller than Ganymede and Titan Monde. This high density is the result of the internal structure of Mercury has a relatively large iron core, which can be completely or partially melted. A large iron core also generates a weak magnetic field about 1 percent as strong as the country. Despite this weak magnetic field to be Mercury allows a very thin atmosphere to hold in what is called the magnetosphere. Until 1962 it was believed that Mercury rotated on its axis once each time it orbited the sun This means that a Mercury side always facing the sun in the same way one side of the country Moons is always the earth. Mercury actually rotates about its axis three times in the course of two of its orbits around the Sun.
If you were standing on Mercury you would see the sun rise and then grow in size. After tracing paths the sun then stop again and resume their original course. Mercury's orbit is even stranger, as a result of being close to the sun, where the Suns gravitational field is incredibly strong. Since Mercury orbits the Sun the point where Mercury starts a new orbit moves slightly. For some time, the hypothesis that another planet Vulcan was also called, their attraction was exerted on Mercury, and this caused the precession of the perihelion. On 3 August 2005, NASA launched a new mission to Mercury MESSENGER named, which means Mercury geochemistry surface environmental space and Ranging.
The MESSENGER spacecraft will make three flybys of Mercury in January 2008, October 2008 and September 2009. The MESSENGER move then into orbit around Mercury in March 2011 in Japan and the European Space Agency are also a joint mission to Mercury planning called BepiColombo, which Mercury in 2019 will these satellites use a variety of scientific instruments reach us to tell more about all aspects of the planet Mercury.
