Russian scientists calculated that the comet C/2013 A1 could cause an explosion of 20,000 million megatons and open a crater 500 km in diameter on the surface of Mars to hit this planet in October 2014.
If a collision occurs, the comet would impact against Mars at a speed of 56 kilometers per second and the crash would open a crater two miles deep.
It is expected that on October 19 the MRO orbiter NASA can capture images in high resolution C/2013 A1, because the comet will have a brightness of 8 of the apparent magnitude of a star.
Comet C/2013 A1 was discovered earlier this year by Australian astronomers Siding Spring Observatory.
COMMENT:
I just hope nothing happens and everything is false alarm.
