      On Tuesday, a quarter-mile-wide space rock will pass within 202,000 miles of our planet at 6:28 p.m.

      Scientists have been tracking the asteroid that is the size of an aircraft carrier, and say the encounter will be close enough to be in the moon TMs orbit, but far enough to be invisible to the naked eye and pose no threat.

      Experts at NASA TMs Near-Earth Object Program, which monitors asteroids and comets, say there TMs zero chance of an impact. They plan on using the close encounter to learn more about the asteroid that TMs known as 2005 YU55.

      Antennas at NASA TMs Deep Space Network in California have been tracking the spinning asteroid, since late last week.

      The last time one this big zipped by Earth was in 1976.

      If you are interested in catching a glimpse of the space rock, amateur skygazers with a 6-inch telescope or larger can see the asteroid if skies are clear, and you know where to look.
