It has been a month since the discovery of our observatory’s second near-Earth asteroid, and during that month the precision of its orbit has significantly improved. On the basis of new data we can attempt a glimpse into the future.
So, asteroid 2011 QY37 came closest to the Earth on Sept. 24th, passing 0.7 a.u. from our planet. The asteroid is a rather large body and will be observable from our observatory until the beginning of next year. Thus, its observation arc has increased to 5 months.
The next close approach of asteroid 2011 QY37 will be more favorable; in November of 2015 it will pass 0.4 a.u. from Earth, achieving a maximum brightness of magnitude 18.4. At that apparition, we will be able to observe the asteroid for half a year. The next time 2011 QY37 comes close to the Earth at the end of November 2019, it will reach mag. 17.6! It will pass at an absolutely safe distance of 0.3 a.u. This approach will be the closest for this asteroid in the near future. In 2024 it will pass 0.68 a.u. from the Earth with a maximum brightness of mag. 19.3.
At the beginning of 2012 we will increase the precision of the asteroid’s orbit, and we will return again to the analysis of future approaches of this harmless celestial body. Remember, the next close approach of another near-Earth asteroid discovered at our observatory – 2010 RN80, will take place in 2037!
