24 hour WARNING! Asteroid discovered today can take out satellites May 29… this is not 2012 KP24 and twice as close!!!

Discovered just today, 2012 KT42 is a small Apollo class near-Earth asteroid which will fly by us May 29th:

EARTH — 0.00014 AU / .05 LD
MOON — 0.00241 AU

Condition Code or orbit uncertainty estimate is a 7 on a scale of 0-9, with 0 being good, and 9 being highly uncertain.
