Two potentially hazardous asteroids have been ruled out as a threat to Earth — but a bigger one is on the way
- The National Aeronautics and Space Administration (
NASA) has ruled out two potentially hazardous asteroids as a threat to Earth.
- Asteroids 2010 CO1 and 2000 QW7, though large in size, are not a collision course for Earth.
- But in little over a month, asteroid 1998 HL1 -- bigger than Burj Khalifa -- will be flying by.
