Small Asteroid PASSED CLOSER THAN TV SATELLITES

A small space rock made an extremely close approach yesterday (October 19, 2018). The close flyby of Asteroid 2018 UA occurred just hours after being detected by the Catalina Sky Survey in Arizona.

Limited observations did not allow for precise trajectory calculations, but estimates suggest the small asteroid passed at a distance between 4,536 miles to 9,540 miles (7,300 km to 15,353 km) from Earth’s surface. For comparison, meteorological and television satellites orbit at some 22,300 miles (35,888 km) from our planet’s surface, which means the asteroid’s approach was one of the closest registered.
