2What do scientists say about the collision of an asteroid with Earth? A) It is very unlikely but the danger exists. B) Such a collision might occur once every 25 years. C) Collisions of smaller asteroids with Earth occur more often than expected. D) It‘s still too early to say whet...
"Current calculations show the chance of collision is extremely unlikely with no cause for public attention or public concern," that ranking categorization states. All of the other 1,448 asteroids on the Risk List have a scale ranking of 0. The ESA currently estimates that the asteroid has a ...

The asteroids are very fragile, but when they are this large they may penetrate deep into the atmosphere and pose a real threat of collision with Earth, it added. The study urges further research to obtain "a better description of this real source of potentially hazardous objects large enough...
根据最后一段“If any of those asteroids turns out to be on a collision course with Earth, the DART mission shows that changing its orbit is a realistic possibility.”(如果这些小行星中的任何一颗与地球发生碰撞,DART任务表明改变其轨道是一种现实的可能性。)可知,DART任务的意义是为小行星撞击提供解决...
WASHINGTON, Sept. 18 (Xinhua) -- An international team of scientists found that a collision in the asteroid belt 470 million years ago diversified life on Earth. The study published on Wednesday in the journal Science Advances showed that the breakup of a major asteroid between Jupiter and Mars...
