What was the size of the Russian meteor?

The Russian fireball likely produced the most powerful such space rock blast since a 130-foot (40 m) object exploded over Siberia in 1908, flattening 825 square miles (2,137 square km) of forest. Preliminary reports suggest that the Chelyabinsk fireball’s parent asteroid was composed primarily of stone, with a smidge of iron thrown in.

How big was the asteroid that hit Russia?

The Russian meteor struck just hours before the 130-foot asteroid 2012 DA14 gave Earth a close shave, missing our planet by just 17,200 miles (27,000 km). But the two space rocks are unrelated, researchers say, making Feb. 15 a day of remarkable cosmic coincidences. You can see the Arxiv paper on the Russian meteor here.

How big was the meteor that hit Earth in March 2013?

On 1 March 2013 NASA published a detailed synopsis of the event, stating that at peak brightness (at 09:20:33 local time), the meteor was 23.3 km high, located at 54.8°N, 61.1°E. At that time it was travelling at about 18.6 kilometres per second (67,000 km/h; 42,000 mph) —almost 60 times the speed of sound.
