GRAND RAPIDS, Mich. (March 5,2014) — A rock measuring about 100 feet across zipped by Earth at around 4 p.m. EST on Wednesday March 5. NASA reports that the closest the asteroid, 2014 DX110, will get to the planet is about 217,000 miles. Scientists say this is a safe distance away. Asteroids safely pass by the planet about 20 times per year.
The asteroid was detected through a NASA program called “Spaceguard.” According their website, scientists track and characterize asteroids and comets using both ground and space based telescopes.
