What is Solar System?

To judge whether a substance is a celestial body, it can be summarized by “three points”: Firstly, whether it is a form of existence of matter in the universe. Although the interstellar substance is invisible to the naked eye, it is a celestial body;square steel tubing the second is to see if it is a universe. The material, the celestial body is not a celestial body; the third is to see if it is located in the Earth’s atmosphere, the celestial body in the outer space, and not the celestial body in the Earth’s atmosphere. As all we known, solar system is one of celestial bodies.

The solar system is centered on the sun and is a collection of all celestial bodies constrained by the gravitational pull of the sun. Includes eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), and at least 173 known satellites, 5 identified dwarf planets and hundreds millions of solar system small objects. Broadly speaking, the solar system includes the sun, four inner planets like the Earth, an asteroid belt made up of many small rocks, four huge outer planets filled with gas, and a small small rock filled with frozen rocks called the Kuiper Belt. Celestial area. Among them, there are eight major planets in the solar system, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.tin plate suppliers

The sun is a typical star of the Milky Way. It is located on the arm of the branch cantilever, with 26,100 light years away from the center of the Milky Way. The solar system moves at a speed of about 240 km/s and turns 226 million years. The eight planets in the solar system are all running in nearly circular orbits of almost the same plane, orbiting the sun in the same direction. Except for Venus, other planets have the same direction of rotation and the same direction of revolution. The revolving directions of the comets are mostly the same, most of them are elliptical orbits, and the general revolution period is relatively long. There are eight celestial bodies that can be called big planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The orbits that orbit the sun are divided into three categories: planets, dwarf planets, and solar system small objects. On August 24,2006, the 26th International Astronomical Union was held in Prague, Czech Republic, to redefine the term planet, first to exclude Pluto from the outer planet, and to make a new classification of Pluto, Ceres and Eris: Dwarf planet.Steel Pipe Suppliers Dwarf planets do not need to remove small objects near the orbit. Other celestial bodies that may become dwarf planets include Sedna, Ergos and Clarion. From the first discovery of 1930 to 2006, Pluto was regarded as the ninth planet of the solar system. But in the late 20th and early 21st centuries, many celestial bodies similar in size to Pluto were discovered in the solar system. In particular, the sacred star was more clearly pointed out than Pluto, making Pluto’s status seriously threatened.
