What were you doing between about 9:30-10:30pm on July 20? If you answered anything but screaming your head off because “There’s an asteroid-a-comin’!” then you’re probably correct…because you didn’t know. No one did, that is until a few days after the close call happened. A high-tech telescope in Hawaii discovered that an asteroid got about 1/3rd of the “Earth-Moon” distance to Earth.
According to the Florida Space Report, “A space rock now designated as asteroid 2017 OO1 was detected on July 23, 2017 from the ATLAS-MLO telescope at Mauna Loa, Hawaii. An analysis of its trajectory revealed it had been closest to Earth on July 20 sometime between 10:27 p.m. to 11:32 p.m. EDT (between 02:27 to 03:32 UTC on July 21).”
Pretty scary right? The likelihood of something like this actually colliding with Earth is pretty small, however the fact that it wasn’t discovered until it would have been too late is unnerving. What’s also unnerving? The asteroid in question “is about three times as big as the house-sized asteroid that penetrated the skies over Chelyabinsk, Russia in February, 2013, breaking windows in six Russian cities and causing more that 1,000 people to seek treatment for injuries, mostly from flying glass.”
