Before assuming an asteroid is going to kill us all, take a deep breath and open up the NASA’s Near Earth Object (NEO) program website to check your information, the agency suggests in a statement regarding a so-called threatening asteroid making the rounds in media reports.
Data from the Minor Planet Center shows that the quarter-mile-wide asteroid 2014 UR116 won’t pose a threat to Earth or any other planet in the next 150 years or more, the agency said.

The severity of an impact is directly proportional to the speed in which the object travels. Kinetic energy is based on motion and increases with speed. So an object that is 1/4 mile wide…. or 440 yards that’s 4 and a half football fields wide. At speed, say 20k miles per hour, it would pose a significant threat. at 200k miles per hour, it could cause half the planet to starve in a few years….. at 2 million miles per hour, it would sterilize the earth.
But that’s ok… because the biggest liars on the planet state that it poses no threat.
