• Mercury is the closest the planets of the solar system to the sun, and the second-smallest planet in the system, diameter 40% smaller than Earth and 40% larger than the moon, is the smallest of Jupiter moon Ganymede and Saturn's moon Titan.

•    Date of Mercury are similar to Earth's history, since about 4.5 billion years ago when a planet formed the planets of the solar nebula by the theories of the group. Have passed the group shortly bombardment great, and in the early and during a planet marked the heart of a metal heavy and crust of silicates, and after a bombardment great poured lava over the land of the planet and covered the cortex of old, and during this time gathering the debris of rocks and stones on the planet and entered into a new phase in which stabilized When the crust subsided ejaculation.

•  Mercury that the world is like the moon, full of holes, depressions and has a giant, and many of the lava. Drilling range in size from 100 meters to 1300 kilometers. The largest crater on Mercury is Kaloris basin (Caloris) have been identified by Hartmann and Kuibir (1962) In the opinion of scientists that any hole larger than 200 km in diameter is the basin.

• As it seems that Mercury can not be supported by the presence of water in which the presence of an atmosphere very light Odhu heat cocktails throughout the day, but in 1991 took scientists radio waves and found the glitter of the North Pole of the planet, can be interpreted as the snow on or within its surface, but You will probably be snow on Mercury with this proximity to the sun?.

  New discoveries

• Announced in July 2008 by a group of scientists Thomas Zorbouchn which tracks Messenger space probe, the results indicate the presence of water in the atmosphere of Mercury light, which was a surprise to scientists with him, where it is difficult to the existence of that on Mercury due to its proximity to the sun. The studies revealed that provided by the Messenger spacecraft to the planet's diameter has shrunk by 1.5 km and the reason for this is because scientists to slow decline to the heat of the molten heart of the planet and this process increases the intensity of the magnetic field of the planet.

•    Also showed composite indices pictures on the activity of Mercury's volcanic past and also suggests measuring the magnetic to the presence of fluid in the heart of the planet, have been found scientists evidence of volcanic activity interview on Mercury, as shown photographs taken by the vehicle and the existence of large areas of the planet's surface is covered Balfohat also showed a volcanic crater Keiber image which is located south of the center of Mercury has been detected from a circular basin with a diameter of 83 miles called Bolivnotos, also showed images that volcanic eruptions were the cause in the formation of most of the surface of Mercury.
