Travelers In The Night

Asteroid hunters have become aware of the many small space rocks which come near Earth because of improvements made to telescopes, cameras, and computer analysis software. Recently, my Catalina Sky Survey teammate Rose Matheny used her skills and a new camera to discover the second small space rock in 32 days which came between the communications satellites and the Earth's surface. Rose spotted her 10 to 12 foot diameter space rock as it approached the Earth more than a million miles away with its little full moon face pointing towards us. 31 hours later, her discovery, 2017 GM, came to within 10,100 miles of Earth as it streaked by at about 11 mi/s on its way towards an encounter with Venus five and a half weeks later. It it had been on an impact trajectory with our planet, Rose's early detection would have allowed asteroid hunters to alert humans to prepare for a spectacular light show as it exploded in our atmosphere.
