On March 15, 2016, astronomers detected a space rock – now designated as asteroid 2016 EF195 – using the PanSTARRS 1 telescope at Hawaii. Surprisingly, as they analyzed its trajectory, they realized it had been closest to Earth on March 11 at 03:52 UT (March 10 at 10:52 pm ET). This means the asteroid’s closest approach occurred 4 to 5 days before it was seen. Moreover, they realized that asteroid 2016 EF195 flyby had passed at about 23,900 miles (38,463 km) from the surface of our planet, or about 0.1 the Earth-moon distance.
