Some of the scientists believe that the way the Solar System formed, that the Sun when it collapsed and actually created the Sun, a lot of the dust around it created rings and then the particles in those rings accumulated together, and they formed bigger rocks, and then that's how the planets, you know, were formed.
一些科学家相信，太阳系就是这样形成的， 当太阳诞生的时候， 有很多尘埃围绕着它 然后在环中有些东西聚集在一起， 然后形成大岩块，然后形成行星， 这样形成。
