As reported in Wired News:
An asteroid 30 to 50 feet across will pass by the Earth at just more than one-third the distance between the Earth and the moon on Wednesday. That’s the closest near-Earth object approach currently known between now and the flyby in 2024 of a similar-size object known as 2007 XB23.
The new asteroid, called 2010 AL30, was discovered by the NASA-funded Lincoln Near-Earth Asteroid Research program, and announced Monday by the Minor Planet Center at the Smithsonian Astrophysical Observatory.
The short amount of time between the spotting of the object and its near intersection with Earth is a good reminder that humans don’t know every object that could come hurtling out of space and collide with our planet.
“Visitors frequently ask me if I worry about the NEOs that I measure,” wrote Dr. P. Clay Sherrod of the Arkansas Sky Observatories, on a forum thread discussing the asteroid. “My response: ‘I don’t worry about those that we keep up with…. I am more concerned about the ones we never see coming.”
