(Russian) Пролет астероида 2011 CQ1 над Южной Америкой

Update of the orbit of asteroid 2011 CQ1

The Minor Planet Center has just updated the orbit of the asteroid based on new measurements received by the Moriyama Observatory.

New data support a close flyby at a distance of ~5500 km from the surface of the Earth! Asteroid 2011 CQ1 belongs to the rarest family of NEOs – Atens. Right now the asteroid is moving toward its encounter with Earth and is about 50,000 km away.

2011 CQ1 may come even closer!

On the basis of the latest measurements, it appears that the object will pass still closer. It is quite likely that the asteroid will pass only 5500 km above the surface of the Earth! Stay with us and follow the news!

Ultra-close passage of asteroid 2011 CQ1

Today at 23:45 (MSK) a small asteroid with a diameter of several meters will fly by the Earth. Asteroid 2011 CQ1 was discovered by the Catalina Sky Survey several hours ago. The asteroid should pass 21,000 km from the Earth, that is practically twice as close as geostationary satellites. At maximum brightness (mag. ~14.5m) the object will be visible in large amateur telescopes far from the city.
