无论它们如何形成,土星的环都会随着时间的推移而不断变化,随着较小的物体过于靠近而获得物质。根据卡西尼号任务期间收集的数据,科学家认为这些环吸引了行星际尘埃,这有助于补充随时间流逝而丢失的物质。牧羊圈内环内的活动也会引起环的变化。科学家们对电流环如何消散有很多理论,但大多数人认为它们可能不会持续很长时间。只有当某些东西足够接近撕裂时才能形成新的戒指。其他较小的粒子,虽然被附近的卫星赶来,但可能会扩散到太空并丢失到系统中。随着卫星本身向外迁移,它们“放牧”的环粒子会扩散开来。粒子可以“下雨”进入土星,或消散到太空。此外,与流星体的轰击和碰撞可能会将粒子撞出轨道。随着时间的推移,这些行为可能导致戒指质量减少并最终完全消失。卡西尼数据指出,目前的环最多可能是几亿年前的。它们可能只能持续一亿年才能消散到太空或进入地球。这意味着与地球本身相比,土星的环是短暂的,并且由于较小的世界在土星的一生中过于徘徊,所以这个星球可能有许多环。科学家在时间上达成一致的一件事意味着在一个星球的生命周期中有不同的东西,我们将能够更好地欣赏土星的惊人戒指数千年。

加拿大艾伯塔省天文论文代写:进入地球

No matter how they are formed, Saturn’s rings will change over time, getting material as smaller objects get too close. According to data collected during the Cassini mission, scientists believe that these rings attract interplanetary dust, which helps to replenish substances that have been lost over time. Activities within the inner ring of the shepherd ring can also cause changes in the ring. Scientists have a lot of theory about how current loops dissipate, but most people think they may not last long. A new ring can only be formed when something is close enough to tear. Other smaller particles, although coming by nearby satellites, may spread into space and be lost to the system. As the satellites migrate outward, their “grazing” ring particles will spread. Particles can “fall” into Saturn or dissipate into space. In addition, bombardment and collision with meteoroids may knock particles out of orbit. Over time, these behaviors may cause the ring to lose weight and eventually disappear completely. Cassini data pointed out that the current ring may be hundreds of millions of years ago. They may only last for 100 million years to dissipate into space or into the earth. This means that Saturn’s ring is short-lived compared to the Earth itself, and because the smaller world is too embarrassing in Saturn’s life, the planet may have many rings. One thing scientists agree on in time means that there are different things in the life cycle of a planet, and we will be able to better appreciate Saturn’s amazing ring for thousands of years.
