There are so many unknowns waiting for human to explore in the vast universe. Among them, there is a kind of material known as "extraterrestrial stone" which is loved by people. This kind of material is meteorite. It refers to the meteorite debris falling on the ground, which is composed of iron, nickel, silicate and other minerals, also known as meteorite.
石铁陨石又称陨铁石，占陨石数量的2%-4%，这类陨石中硅酸盐与镍铁合金的含量各占50%。
Ferrometeorites, also known as meteorites, account for 2% - 4% of the total number of meteorites. The contents of silicate and ferronickel in these meteorites account for 50% respectively.
重：363g（Weight: 363g）
吴先生此块石铁陨石，呈不规则形，色泽黄黑，有磁性。陨石表面布有大小不一、深浅不等的凹坑，即熔蚀坑。坠落地面后，由于高温，在冷却后附着了些许砂粒留于表面。其陨石特征明显，密度大、比重重，微磁性，表面呈现铁的光泽，并且表面有明显陨石坑洞和疤痕。
Mr. Wu's iron meteorite is irregular in shape, yellow and black in color, and magnetic. Craters of different sizes and depths are distributed on the surface of meteorites, i.e. erosion craters. After falling to the ground, due to the high temperature, some sand particles are attached to the surface after cooling. Its meteorites are characterized by high density, heavy ratio, micromagnetism, iron luster on the surface, and obvious craters and scars on the surface.
高温烧灼痕迹，熔融状态和硫化物明显，且此块石铁陨石中硅酸盐与镍铁合金比例相当。具有很高的科研价值、观赏价值和考古价值，收藏价值和经济价值。
High temperature burn marks, melting state and sulfide are obvious, and the proportion of silicate and ferronickel in this rock is similar. It has high scientific research value, ornamental value, archaeological value, collection value and economic value.
据史料记载，陨石历来被古人当做神石供奉，用来避祸消灾。随着人类文明不断发展和科学技术逐步发达，在上世纪六十年代，美、俄太空飞船登月成功，更激起了人类渴望上星球的欲望，做为“天外来石”的陨石则成为了人类研究和开发外太空星球的重要物证，为人类认识和开发利用外太空提供了大量的科技信息。
According to historical records, meteorites have always been worshipped as gods by the ancients to avoid disasters. With the continuous development of human civilization and the gradual development of science and technology, in the 1960s, the success of American and Russian spacecraft landing on the moon aroused the desire of human beings to go to the planet. As the "extraterrestrial rock", meteorite has become the important material evidence for human research and development of outer space planet, and has provided a lot of scientific and technological information for human understanding and development of outer space.
