August 27th at the ISON-NM Observatory, a new, second near-Earth asteroid was discovered, receiving the designation 2011 QY37. The object belongs to the Amor family and presents no hazard to the Earth. The minimum distance of its orbit to Earth’s is more than 39 million kilometers. The asteroid orbits on a rather extended orbit (eccentricity 0.51), with a period of 3.91 years.

Closest approach to the Earth will happen Sept 25th, when asteroid 2011 QY 37 passes 0.7 a.u. from our planet (104.7 million km). The next few years will be favorable for observing this object. In November 2015 it will reach 18th magnitude at a distance of 0.31 a.u. In January 2020, 2011 QY37 will be a little farther with a brightness of magnitude 18.5.

Although this is a preliminary prediction, the accuracy of the orbit will improve. We will be able to observe this object until the beginning of the next year. After that we will certainly return to this asteroid again.

Remember, our first near-Earth asteroid was discovered Sept. 10, 2010 and received the designation 2010 RN80. In addition, another near-Earth object is a second comet – P/2011 NO1, discovered at the ISON-NM Observatory in July of this year.
