Asteroid 2011 CC22 passes the Earth.

Asteroid 2011 CC22 passed by the Earth at a distance of about 5 920 000 km (15.4 times the average distance between the Earth and the Moon, or 3.96% of the distance between the Earth and the Sun), slightly after 7.20 am GMT on Friday 4 August 2017. There was no danger of the asteroid hitting us, though were it to do so it would have presented a significant threat. 2011 CC22 has an estimated equivalent diameter of 120-380 m (i.e. it is estimated that a spherical object with the same volume would be 120-360 m in diameter), and an object of this size would be predicted to be capable of passing through the Earth's atmosphere relatively intact, impacting the ground directly with an explosion that would be 60 000-1 500 000 times as powerful as the Hiroshima bomb. Such an impact would result in an impact crater about 4-5 km in diameter and devastation on a global scale, as well as climatic effects that would last decades or even centuries.

2011 CC22 was discovered on 6 February 2011 by the University of Arizona's Mt. Lemmon Survey at the Steward Observatory on Mount Lemmon in the Catalina Mountains north of Tucson. The designation 2011 CC22 implies that the asteroid was the 1103rd object (object C22) discovered in the first half of February 2011 (period 2011 C).

2011 CC22 has a 434 day orbital period and an eccentric orbit tilted at an angle of 34.8° to the plane of the Solar System, which takes it from 0.99 AU from the Sun (i.e. 99% of he average distance at which the Earth orbits the Sun) to 1.25 AU from the Sun (i.e. 125% of the average distance at which the Earth orbits the Sun). It is therefore classed as an Apollo Group Asteroid (an asteroid that is on average further from the Sun than the Earth, but which does get closer). This means that close encounters between the asteroid and Earth are extremely common, with the last having occurred in February this year and the next predicted in July 2023. As an asteroid probably larger than 150 m in diameter that occasionally comes within 0.05 AU of the Earth, 2017 MB1 is also classified as a Potentially Hazardous Asteroid.
