NASA warns of multiple asteroids approaching Earth at alarming speeds.

NASA's telescopes have detected an asteroid named 2017 UJ2, which is set to make an alarmingly close approach towards Earth on June 7 at a speed of 20261 kmph. The asteroid, almost the size of a car, will be just 1.26 million miles away from Earth, but poses no immediate threat as a potentially hazardous asteroid due to its size. NASA uses ground-based telescopes and its NEOWISE spacecraft to locate near-Earth celestial objects.
