非常抱歉,回答时记忆有所偏差,经评论提醒,现做出更改;为之前没有考证的不负责的行为道歉:

该图为STEREO(日地关系天文台SolarTerrestrialRelationsObservatory)拍摄的2011/10/1日,一颗彗星接近太阳并解体的视频;彗星在接近太阳过程中解体,但随即就发生了日冕物质抛射,使人不免认为他们有一定联系。如果是地球大小的行星撞击,日冕抛射物很可能直接把地球吹散

A bright comet headed right towards the Sun and disintegrated (Oct. 1, 2011) as observed by STEREO's suite of coronagraphs. It was a sungrazing comet of the type known as a Kreutz sungrazer and a particularly bright one at that. Most sungrazing comets have orbits that take them very close to the Sun without actually quite hitting it. However, getting so close almost always destroys these comets, so we see them going in, but not going back out. It appears that the coronal mass ejection seen blasting out into space began before the comet went behind the occulting disk in the COR1 images.

The question of whether a sungrazing comet can somehow trigger a coronal mass ejection is an intriguing one. So far, the feeling is that apparent relationship between some comets and some mass ejections is simply one of co-incidence. At this stage of the solar cycle, the Sun is producing many mass ejections--in fact there were several earlier in the day--and it probably just happened by chance that one of them was around the same time as the approach of the comet. Some researchers have been looking for a more direct relationship, but nothing as yet has come out of these efforts.

原答案:

一张图,小行星撞击太阳的录像

人们现在对太阳的理解还很浅薄,无法解释日冕物质抛射与小行星撞击之间的关系与转换过程

但是诸如此类录像让人不免认为他们有一定联系,如果是地球大小的行星撞击,日冕抛射物很可能直接把地球吹散
