Just saw this little snippet over at SpaceWeather.com:
Newly-discovered asteroid 2012 KT42 is flying past Earth today (May 29th) only ~14,000 km above the planet’s surface. This means 2012 KT42 will actually fly inside the Clark Belt of geosynchronous satellites. The 3- to 10-meter wide asteroid ranks # 6 on the top 20 list of closest-approachers to Earth.
Don’t think this will be viewable by the naked eye, but then again, maybe that’s a good thing.
