【摘要】：正實(shí)驗(yàn)與計(jì)算模擬顯示,小行星表面大、小巖石的分離來源于轟擊表面的顆粒與已經(jīng)存在的巖石發(fā)生的碰撞。糸川(Itokawa)是由巖石堆積而成的小行星,是太陽系中的碎片經(jīng)由自身的重力聚集而成。它具有不規(guī)則的形狀,最大長度只有540 m。2005年,日本"隼(Hayabusa)號"無人探測飛船近距離地拍攝了它的照片,并出人意料地揭示了它的兩種不同的表面類型。表面凹陷的區(qū)
[Abstract]:Positive experiments and numerical simulations show that the separation of large and small rocks from the surface of the asteroid comes from collisions between particles on the surface of the bombardment and existing rocks. Itokawaa is an asteroid formed from the accumulation of rocks. The debris in the solar system is formed by its own gravity. It has an irregular shape and its maximum length is only 540 m.2005. The Japanese unmanned spacecraft Hayabusa, the Hayabusa of Japan, took pictures of it from close range. And unexpectedly revealed its two different surface types. The area of the surface depression.
