During this event a stony meteoroid about 50–60 m (160–200 ft) in size [1] [2]: p. 178 exploded at an altitude of 5–10 km (16,000–33,000 ft) over a sparsely populated forest in Siberia. The resulting shock wave flattened an estimated 80 million trees over a 2,150 km 2 (830 sq mi) area, and may have killed 3 people. [1] [3] [4] [5] [6]
However, the 2009 discovery of several NEOs approximately 2 to 3 kilometers in diameter (e.g. 2009 CR 2, 2009 HC 82, 2009 KJ, 2009 MS and 2009 OG) demonstrated there were still large objects to be detected. One of the 7,000 buildings damaged by the 2013 Chelyabinsk meteor

Some of the smallest asteroids discovered (based on absolute magnitude H) are 2008 TS 26 with H = 33.2 [13] and 2011 CQ 1 with H = 32.1 [14] both with an estimated size of one m (3 ft 3 in). [15] In April 2017, the IAU adopted an official revision of its definition, limiting size to between 30 μm (0.0012 in) and one meter in diameter, but ...
