Asteroid set for close encounter
An asteroid is set to pass within 217,000 miles from Earth - closer than the moon.
But astronomers say it will pose no danger.
The newly discovered asteroid, called 2014 DX110, will hurtle between the moon and Earth on Wednesday. The moon is on average 238,000 miles from Earth.
The asteroid is an estimated 45 to 130 feet across.
Relatively close approaches like this occur all the time, although DX110 is extra close.
