Small Asteroid to Pass Close to Earth March 5

A small asteroid that two years ago flew past Earth at a comfortable distance of about 1.3 million miles (2 million kilometers) will safely fly by our planet again in a few weeks, though this time it may be much closer.

During the upcoming March 5 flyby, asteroid 2013 TX68 could fly past Earth as far out as 9 million miles (14 million kilometers) or as close as 11,000 miles (17,000 kilometers). The variation in possible closest approach distances is due to the wide range of possible trajectories for this object, since it was tracked for only a short time after discovery.

Update: Small Asteroid to Pass Close to Earth March 8 (2013 TX68)

Additional observations of asteroid 2013 TX68 have been obtained, refining its orbital path and moving the date of the asteroid's Earth flyby from March 5 to March 8.

The observations, from archived images provided by the NASA-funded Pan-STARRS asteroid survey, enabled scientists at NASA's Center for Near-Earth Object Studies (CNEOS) at the Jet Propulsion Laboratory in Pasadena, California, to refine their earlier flyby and distance predictions, reconfirming that the asteroid poses no threat to Earth.

"We already knew this asteroid, 2013 TX68, would safely fly past Earth in early March, but this additional data allow us to get a better handle on its orbital path," said Paul Chodas, manager of CNEOS. "The data indicate that this small asteroid will probably pass much farther away from Earth than previously thought."
