A huge asteroid will pass closer to Earth than the moon Tuesday, giving scientists a rare chance for study without having to go through the time and expense of launching a probe, officials said.
Earth’s close encounter with Asteroid 2005 YU 55 will occur at 6:28 p.m. EST Tuesday, as the space rock sails about 201,000 miles from the planet.
“It is the first time since 1976 that an object of this size has passed this closely to the Earth. It gives us a great — and rare — chance to study a near-Earth object like this,” astronomer Scott Fisher, a program director with the National Science Foundation, said Thursday during a Web chat with reporters.
