NASA says a newly discovered asteroid will whiz harmlessly past Earth on Thursday.
The asteroid dubbed 2010 GA6 will safely fly by the planet.
At the time of its closest pass, the 22m-wide space rock will be 359,000km away from Earth. That's about 26,000km closer than the moon.
NASA routinely tracks asteroids and comets that make close approaches to Earth. In January, another small asteroid made an even closer approach to Earth, passing within 122,000km.
