Asteroid to Make Rare Close Flyby of Earth January 29

Scientists are monitoring the orbit of asteroid 2007 TU24. The
asteroid,
believed to be between 150 meters (500 feet) and 610 meters (2,000
feet)
in size, is expected to fly past Earth on Jan. 29, with its closest
distance being about 537,500 kilometers (334,000 miles) at 12:33 a.m.
Pacific time (3:33 a.m. Eastern time). It should be observable that
night by amateur astronomers with modest-sized telescopes.
Asteroid 2007 TU24 was discovered by the NASA-sponsored Catalina Sky
Survey on Oct. 11, 2007. Scientists at NASA's Near-Earth Object
Program
Office at the Jet Propulsion Laboratory in Pasadena, Calif., have
determined that there is no possibility of an impact with Earth in the
foreseeable future.
"This will be the closest approach by a known asteroid of this size or
larger until 2027," said Don Yeomans, manager of the Near Earth Object
Program Office at JPL. "As its closest approach is about one-and-a-
half
times the distance of Earth to the moon, there is no reason for
concern.
On the contrary, Mother Nature is providing us an excellent
opportunity
to perform scientific observations."
Asteroid 2007 TU24 will reach an approximate apparent magnitude 10.3
on
Jan. 29-30 before quickly becoming fainter as it moves farther from
Earth. On that night, the asteroid will be observable in dark and
clear
skies through amateur telescopes with apertures of at least 7.6
centimeters (3 inches). An object with a magnitude of 10.3 is about 50
times fainter than an object just visible to the naked eye in a clear,
dark sky.
NASA detects and tracks asteroids and comets passing close to Earth.
The
Near Earth Object Observation Program, commonly called "Spaceguard,"
discovers, characterizes and computes trajectories for these objects
to
determine if any could be potentially hazardous to our planet.
