Between 25 and 55 (dia)metres. No global killer, but enough to flatten Brussels and it's bureaucrats 
"Blink and you missed it: Asteroid came within 90,000 km, only one sky-watcher saw it
SONEAR sees 25-metre-plus rock when it was, well, so near
A small asteroid made a rare, close pass between Earth and the moon on August 28.
2016 QA2 is estimated by the Minor Planet Center (MPC) as being somewhere between 25 and 55 metres in diameter – so small that it nearly passed without notice.
The MPC's note about the asteroid attributes its discovery to Brazil's SONEAR Observatory, which made this Facebook announcement on August 27.
Its size was calculated as being between 25 and 55 metres – and that puts it as larger than the object that exploded in the atmosphere over Chelyabinsk in February 2013, breaking windows and injuring more than 1,000 people."
