NASA has announced that the asteroid 2007 FT3 is on a collision course with Earth, it weighs approximately 54 million tons. What kind of damage is it going to do if it hits land vs the ocean? Is it as bad as the dinosaur asteroid? Can we nuke it?
In either scenario, the potential energy release is equivalent to detonating 2.6 billion tons of TNT, causing significant regional destruction but not global damage.
However, a Nasa spokesperson told the Standard: “There are no known asteroid impact threats to Earth at any time in the next century. Nasa and its partners diligently watch the skies to find, track, and categorise asteroids and near-Earth objects (NEOs), including those that may come close to Earth.

“The speed of the meteorite is a bigger factor than weight. But at its size and speed it would be more of a Hiroshima or Barringer crater event on land.”
The earth will be reset. The human beings will become homo-saur. The global warming will stop instantly. Million years later, whatever intelligent species will scratch their heads (if they have one) to figure out what the ape-like mammals did on earth ages ago...
这个可能性，简直吓死人了😱。LOL
不过它也撞不上来，就算是大得多得多的小行星比如造成白垩纪生物灭绝事件那种尺寸的小行星，人类有充足的办法让它在太空解体，最后即使一些小碎片落到地球，也会被大气烧毁。
按照重量估算了一下，直径应该在200-300米左右，比灭绝恐龙的那个小不少，但是也很大可以造成区域性大灾难了
这要看落在哪里了，就算落在海洋里，如果不是深海，引发的海啸可能都能毁灭几个沿海城市，当然这个可能性很小就是了
落入大气层后摩擦损耗，到地面就没有那么大了
