An asteroid estimated to be up to 100 feet wide is set for a close call with Earth tomorrow. The asteroid, named TC4, was discovered in 2012 and scientists have been tracking it ever since. It should pass us at a distance of 27,000 miles above the earth’s surface. To put that in perspective … that’s just one-eighth of the distance between Earth and the moon.
Michael Kelley, who is leading the TC4 observation campaign, said in a statement: “Scientists have always appreciated knowing when an asteroid will make a close approach to and safely pass the Earth because they can make preparations to collect data to characterize and learn as much as possible about it. This time we are adding in another layer of effort, using this asteroid flyby to test the worldwide asteroid detection and tracking network, assessing our capability to work together in response to finding a potential real asteroid threat.”
