109E-121-Three Is A Mystery

Within a time span of one and a half hours, the two telescopes of the NASA funded, University of Arizona, Catalina Sky Survey, discovered three asteroids whose orbits are similar enough to grab one's attention. However, they different enough to keep us from jumping to the conclusion that they are part of an asteroid collision fragment family. There has been some speculation about the possibility of killer asteroid swarms which threaten the Earth. There is no evidence to support these ideas.
