The extremely bright Chelyabinsk meteor was seen over Russia in 2013 when a near-Earth 20m (66 ft) asteroid fell through the atmosphere. The light from the meteor was brighter than the Sun, visible up to 100 km (62 mi) away. Images of the fireball were captured by many video cameras. Some eyewitnesses also felt intense heat from the fireball.
Due to its high velocity and shallow angle of atmospheric entry, the object exploded in an air burst over Chelyabinsk Oblast at a height of around 29.7 km (18.5 mi). The explosion generated a hot cloud of dust and gas leaving many surviving small fragmentary meteorites.
