Fortunately, it doesn't look like there are any large asteroids currently set to collide with Earth any time soon but if you want to check the probability of some of the potentially hazardous asteroids (PHAs) set to fly by Earth before 2020, there is impact risk data here. The far more likely scenario is that we see something smaller and harder to detect, like the Chelyabinsk meteor that struck Russia in 2013.
As many as 25 percent of asteroids that could hit us are thought to be unknown and while they are very, very unlikely to destroy life on the planet as we know it, they could have the power to destroy a city.
So, it seems we don't have to be too concerned about death by asteroid just yet but could NASA be hiding the evidence of aliens? Again, probably not. Thaller believes it's extremely likely we'll all find out about alien life very shortly after the experts.
But whether this will convince everyone, we're not so sure.
