Five Massive Asteroids Approaching Earth at High Speeds.

NASA's Jet Propulsion Laboratory has shared details about five asteroids that will make close approaches to Earth during May. None of these asteroids pose any risk to Earth, but any object larger than about 500 feet approaching Earth within a distance of 4.6 million miles is considered a potentially hazardous object. NASA's Double Asteroid Redirection Test spacecraft slammed into asteroid Dimorphos last year to prove whether an impact of this nature could be used to gently nudge a doomsday asteroid away from Earth.
