A huge chunk of black rock bigger than four city blocks is speeding toward us at more than 30,000 miles an hour. Scientists say the asteroid will miss us, but it will be barely more than 200,000 miles away when it passes Earth at 11:13 p.m. Tuesday, and in cosmic terms that's whisker close.
NASA and astronomers at the Chabot Space and Science Center in Oakland, CA will be tracking the fast-moving object with the center's 36-inch telescope, as will scientists at other observatories around the world.
The scientists have estimated the possible effect which a clash with an asteroid of this size could cause to the Earth and namely – a 7-magnitude earthquake and a 20-meter tsunami, leaving a 6-kilometer crater.
