The numerous injuries and significant damage remind us that what happens in space can affect us all. </p><p>While precise information on the size, mass and composition of the object are yet to be confirmed, videos show a fireball and explosion consistent with an asteroid up to a few metres in size exploding in the atmosphere, possibly several to ten kilometres above the surface.</p><p>In this type of event, if the explosion altitude is less than 10 km or so, the resulting shockwave can cause damage on the ground, such as shattering windows. Debris from the object may be found later.</p></blockquote><p></p>
