Scientists at NASA's Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., have determined that a small object that safely passed Earth on May 21 is more than likely an upper-stage of a rocket that carried a spacecraft on an interplanetary trajectory.

2010 KQ was discovered by astronomer Richard Kowalski at the NASA-sponsored Catalina Sky Survey in the mountains just north of Tucson, Ariz., on May 16. Five days later, it made its closest approach to Earth at a distance just beyond the moon's orbit. The object is departing Earth's neighborhood but will be returning in 2036.

My dotAstronomy pal Edward Gomez from the Las Cumbres Observatory is reporting that a man-made object has been spotted orbiting the sun. First noticed in the Catalina Sky Survey on May 16, it was thought to be an asteroid, but then, because of its very circular and low-inclined orbit, Richard Miles, using the Faulkes Telescope North realized it could be man-made. Now dubbed 2010 KQ, it orbits the Sun every 1.04 years, and on May 21 it came within 1.28 lunar-distances of the Earth. Miles captured this image of the object, above, and spectral analysis of 2010 KQ is consistent with UV-aged titanium dioxide paint. What could it be?
Gomez says Miles believes it could be the 4th stage of a Russian Proton rocket which launched the Luna 23 lunar sample return attempt, which was launched on October 28, 1974 and reached lunar orbit in November of that year.
