ASTEROID DOUBLE FLYBY:  On Sept. 7th, a newly discovered asteroid about the size of a large grey whale flew over the south pole of Earth only 25,000 miles away. For scale, that's only a few thousand miles above the orbits of typical geosynchronous satellites. After the Earth flyby, the space rock turned and headed in the general direction of the Moon, executing a wider flyby of 179,000 miles on Sept. 8th.
