1991 BA is the closest and smallest asteroid yet observed outside the Earth's atmosphere

it is 3-6m in diameter. It passed very close-by to the Earth in 2003 - in fact, it was the closest approach by an asteroid that didn’t hit the Earth that has ever been documented, at a distance of 88,000km. This is less than a quarter of the distance to the Moon, and therefore, much less than 1.3AU,
