New images, video of close-passing 2015 TB145
Boo!
(Below are)... latest radar releases showing 2015 TB145, which swept within 1.3 lunar distances of Earth on October 31, 2015, Halloween in North America. The object passed Earth at a distance of about 302,000 miles (486,000 km). As it passed, it was found to be spherical in shape and approximately 2,000 feet (600 meters) in diameter. It completes a rotation about once every five hours. Observations made last week by scientists using NASA’s Infrared Telescope Facility in Hawaii indicated the object was a comet, an icy body that had likely shed its volatiles after numerous passes around the sun. Meanwhile, in a statement from yesterday (November 3, 2015), NASA’s Jet Propulsion Laboratory continued to refer to the object as an asteroid.
