Approaching Asteroid Has Its Own Moon

NASA is tracking a large near-Earth asteroid as it passes by the Earth-Moon system on May 31st. Amateur astronomers in the northern hemisphere may be able to see the space rock for themselves during the 1st week of June. The closest approach of the asteroid occurs on May 31 at 4:59 p.m. EDT, when the asteroid will get no closer than about 5.8 million kilometers, or about 15 times the distance between Earth and the moon.

Approaching asteroid 1998 QE2 has a moon. Researchers found it in a sequence of radar images obtained by the 70-meter Deep Space Network antenna at Goldstone, Calif., on the evening of May 29th (May 30th Universal Time) when the asteroid was about 6 million kilometers from Earth.
