  1. the smallest planet in our solarsystem what is the smallest planet?Solar planets are a fantastic mixture of what is possible with regard to the creation of planets. From the solar system there are terrestrial planets - bodies consisting mainly of silicate minerals and alloys. And in the external solar system, you have gas giants and organizations consisting mainly of ice, which is located a little further in the Trans-Neptunearea. The question is what will be the smallest planet ever controversial. Until recently, Pluto was considered the smallest planet. But, using the entire IAC Resolution of 2006, which imposes restrictions on what the definition of this planet includes, this status has since passed intoMercury. Size andvolume: With an average radius of 2,440 km, Mercury is the smallest planet in our solar system, the size of 0.38 Earth. And, assuming that he does not encounter flattening at the poles - for example, on Venus, this means that it is an almost perfectly curved body - its radius at the poles is exactly the same as at the equator. And although it is smaller than the most significant natural satellites in our solar system, such as Ganymede and Titan, it is more massive. The mass is 3.3011 × 1023 pounds (33 trillion metric tons; 36.3 trillion US tons), which is equal to 0.055 Earth relative to themass. Because of this, gravity is 3.7 m / s2, which may be 0.38 times greater than that of the Earth (0.38 g). Necessarily this means that if you can stand on the surface of Mercury, you will weigh 38 percent more than onEarth. In terms of volume, Mercury again becomes a little diminishing, at least by earthlystandards. In fact, Mercury has a volume of 6.083 × 1010 km3 (60 billion cubic kilometers; 14.39 billion cubic kilometers), which will be 0.056 times the volume of the Earth. In other words, you can place Mercury on Earth almost twentytimes.

  2. Structure andcomposition: Like Earth, Venus and Mars, Mercury is an earth planet, which means that it is mainly composed of silicate minerals and compounds that differ between the metal core and silicate mantle, as well as the earth'scrust. Ho wever, in the case of Mercury, the core is too large compared to other planets on the planet, its radius is approximately 1800 kilometers (approximately 1118.5 kilometers), and therefore it occupies 42 percent of the volume of this planet (compared to 17 percent).land). To describe this, many theories have been proposed, the most widely recognized of which is that Mercury was the largest planet that collapsed planetesimally, which tore apart most of the first crust and mantle, leaving the core as the most importantelement. Under the core, there are mantles 500–700 km thick (310–435 km), consisting mainly of silicate material. The surface of the Mercury crust, which consists of silicate material with a depth of 100-300 kilometers. Yes, Mercury is a rather small client compared to its brothers, brothers and distant relatives in the solar system. But he is also one of the most dense, hot and irradiated. Thus, being humble, no one ever ascribes to this planet, because it is very fashionable,
