I mean...you have to admit though that would be one hell of a light show.I hear quite a bit about this rock that may be heading in our direction sometime soon. Is it going to nail us?
Unless the astronomers/scientists declare based on measurements, it is false. We are in a time, it is possible to measure huge rocks hurling towards Earth. Remember the rocks that hit the Jupiter--Levy Shoemaker!





Light show, yes, reminds me of the joke,

Unless the government is holding out on us, we have absolutely no knowledge of an asteroid headed toward us.





The chances of anything actually hitting our tiny little planet are remote (but still real).





Is is possible that an asteroid could be barreling at us right this moment, and we wouldn't know about it, because it is very, very difficult to find them. First, they're usually quite small relative to other bodies in the solar system (even our tiny planet). Second, they're very dark (don't reflect much sunlight), and obviously, it's very difficult to see a dark object against a dark sky. Finally, the sky is a HUGE place to look. Not only do our telescopes only able to see tiny fractions of the sky at a given time, but they don't usually spend much time looking at the same place, which further lessons the chances of seeing an incoming asteroid.





No, unlike science fiction movies, we can't look through some infrared telescope to see them because of essentially the same reasons as a visible-light telescope.





Also, VERY unlike science fiction, there is not a radar system to throw into space to detect one.





One of the most powerful radar systems in the world, the Shemya COBRA DANE radar system in Alaska, which is specifically designed to monitor space object, has a maximum range of only about 3,400 miles (5,500km). This means that it often cannot track objects in high orbit, and can't even come close to monitoring anything out in geosynchronous orbits.





We can barely keep track of our own satellites... there's no way to detect an incoming asteroid with radar.





So - as far as we know, there is no asteroid headed our way.
There's a 1 in 400,000 chance that Apophis is going to nail us on April 13, 2036.
