The exquisite asteroid soft enamel pins is an exploration of the purpose. Wearing the asteroid soft Enamel Pins every day, you will feel sunny together. Asteroids are similar planets in the solar system that move around the sun, but are much smaller in size and mass than planets. Up to 2018, about 1.27 million asteroids have been found in the solar system, but this may be only a small part of all asteroids, only a few of which are larger than 100 kilometers in diameter. By the 1990s, the largest asteroid was Ceres, but some of the asteroids found in the Kuiper belt in 2000 were larger than Ceres. For example, the diameter of Varuna in 2000 was 900km, and that of kuoer in 2002 was 1280km. The diameter of ergus in 2004 might even reach 1800km. Sedna asteroid 90377, discovered in 2003, is located outside the Kuiper belt, with a diameter of about 1500 km. It is estimated that there should be millions of asteroids, as detailed in the list of asteroids, while the largest asteroids began to be reclassified as dwarf planets.
The first asteroid to be discovered
The discovery of the asteroid is closely related to the proposal of the Titus bode rule. According to the rule, there should be a planet at a distance of 2.8 astronomical units from the sun. In New Year’s Day 1801, piacci found the first asteroid Ceres. On the evening of January 1, 1801, Giuseppe Piazzi found a star in the constellation Taurus at the observatory in Palermo, Sicily. At first he thought it would not be another comet. But when its orbit was measured, it was found that it was not a comet, but rather a small planet. In the following years, the intelligent God star, marriage God Star and Vesta star with similar orbit to Ceres were discovered one after another. The introduction of astrophotography and the use of flash comparator have greatly increased the annual discovery rate of asteroids. Piazzi himself did not participate in the project to find the “ghost”, but he heard about the project. He suspected that he found the “ghost”, so he continued to observe the star for several days. He reported his findings to the Gotha Observatory, but at first he said he found a comet. After that Piazzi was ill and could not continue his observation. It took him a long time to get to Gotha, when the star was already moving towards the sun and could no longer be found.Later, there was the image of soft enamel pins as a souvenir.
The cause of asteroid formation
There is a speculation that the asteroid’s soft Enamel Pins planet may be the remains of a mysterious planet, which was destroyed by a huge cosmic collision in ancient times.But judging from the characteristics of these asteroids, they don’t seem to have gathered together. If all the asteroids are added together to form a single object, its diameter is less than 1500 kilometers, smaller than the radius of the moon. At first, astronomers thought that an asteroid was formed by the rupture of a planet between Mars and Jupiter, but the total mass of all asteroids in the asteroid belt was smaller than that of the moon. Astronomers believe that asteroids are remnants of the formation of planets in the solar system. Jupiter’s mass grows fastest when it forms in the solar system, preventing another planet from forming in the asteroid belt. The orbits of asteroids in the asteroid belt area are disturbed by Jupiter, and they constantly collide and break up. Other matter is ejected from their orbit and collides with other planets. After the constant collision and rupture, new asteroids were formed. Some of the debris later fell to earth and became meteorites.
