NASA and several professional and amateur stargazing groups will offer live webcasts of the asteroid 2012 DA14 flyby, which will be at its nearest to Earth at 2:24 p.m. EST (1924 GMT). The asteroid is 150 feet (45 meters) wide, about half the size of a football field, and will approach within 17,200 miles (27,000 kilometers) —closer than the planet’s ring of weather and GPS satellites —when it flies by.
