How bigiEstimated from brightness and an assumed albedo. Radar or a spacecraft visit would tighten it.
34m
range 25–57 m
How closeiLD = lunar distance (~384,400 km). The closest the object's path brings it to Earth's centre.
16.0LD
range ≈6,161,340 km
How fastiVelocity relative to Earth at closest approach.
13.1km/s
CompositioniInferred from spectral type. Drives whether an impact would airburst or reach the ground.
Stony
range Stony (assumed)

Impact energyiKinetic energy converted to TNT-equivalent, with the size and speed ranges propagated through.
2.2 Mt
range 871 kt – 10 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.
