2007 TU 24 is a near-Earth asteroid that was discovered by the Catalina Sky Survey on October 11, 2007 . Its elliptical orbit extends beyond the orbit of Mars into the main asteroid belt . Its orbit point closest to the sun is within the earth's orbit. He belongs to the group of Apollo asteroids . With a diameter of around 250 m, it is large enough to wreak regional devastation in the event of an impact on the earth.
Close encounter with the earth on January 29, 2008
As was previously determined during the orbit determination, it flew past the earth on January 29, 2008 at 09:33 am CET at a distance of 554,209 km, which corresponds to about 1.44 lunar orbit radii . It came so close to the earth that radar scans with radio telescopes and spectral surveys of its surface became possible. Even with simple amateur telescopes one could observe the object, which is around 10.5 size classes, on its path.
NASA assured that there was no danger to Earth now or in the near future.
