Armageddon

Remember Armageddon by Bruce Willis back in 1998 where a meteor the size of Texas (approx 696,241 km²) was on a collision course with good old Earth. They managed to change the trajectory of the meteor and it skipped over the Earth's atmosphere and we're all still here today. This is what would have happened if another came our way...

There goes my toy collection!

P.S: Singapore is 707.1 km²
