Frosty Piss writes from a report via CNN: A small asteroid has been found circling Earth. Scientists say it looks like the asteroid, named 2016 HO3, has been out there for about 50 years. Calculations indicate 2016 HO3 has been a stable quasi-satellite of Earth for almost a century, and it will continue to follow this pattern as Earth's companion for centuries to come. Scientists think the asteroid is between 120 and 300 feet (37 to 91 meters) in diameter, and NASA says it never gets closer than 9 million miles (14 million kilometers) from Earth. It was found on April 27, 2016 by the Pan-STARRS 1 asteroid survey telescope in Haleakala, Hawaii. So how do we miss a 300 foot object that has been orbiting the Earth for around 50 years? Probably the same way we've missed all the flying saucers!
