Asteroid 2014 DX110, which is 30 metres across, will make its closest approach to Earth at 4 p.m. ET today, NASA says. At that point, it will be just 350,000 kilometres from Earth, about 35,000 kilometres closer than the moon is, on average.
NASA says the asteroid will pass "safely" and that asteroids pass that close to Earth about 20 times a year.
The asteroid flyby is being streamed live by at least a couple of organizations that connect robotic telescopes to the internet:
- U.S.-based Slooh.
However, Slooh warned that the object's small size, its high speed, and the uncertainty about its orbit means "there is a high probability we will not capture the asteroid during the broadcast."
However, it noted that it will be streaming the flyby of a much larger asteroid called 2014 CU13, which is up to 260 metres in diameter, on Sunday at 10 p.m. ET.
