How bigiEstimated from brightness and an assumed albedo. Radar or a spacecraft visit would tighten it.
38m
range 28–63 m
How closeiLD = lunar distance (~384,400 km). The closest the object's path brings it to Earth's centre.

range 2.3 Mt – 26 Mt
Where that sits
Hiroshima
Chelyabinsk
Tunguska
Tsar Bomba
At this size and speed it would most likely airburst high in the atmosphere — energy between Chelyabinsk 2013 (~0.45 Mt) and Tunguska 1908 (~12 Mt), shown as a bracket, not a single number.
