Encounter With 2013 TX68


October 6, 2013 scientists at Catalina Sky Survey noticed an anomaly approaching Earth on the night side of our planet. For three days asteroid 2013 TX68 basked in feverish observation. Barely time to estimate diameter of 38 meters, woefully short of establishing accurate orbital projections. Three days after raising eyebrows, tracking ground to a halt when 2013 TX68 passed into Earth’s daytime sky.

A few days ago NASA’s Jet Propulsion Laboratory announced March 5, 2016 dawns with a return engagement – a fly-by of indeterminate distance. Uncertain trajectory, the result of brief observation comes with assurances TX68 won’t raise a ruckus. Closest estimates place TX68 at 17,000 kilometers, well within orbital distance of many communication satellites. A far cry from the high range of 14 million kilometers. Blood pressure needn’t rise, science assures we have nothing to worry about – at least not this visit. On September 28, 2017 TX68 returns with an “elevated” dash of concern. As of today, no chance on this lap increases to a 1 in 250 million gamble in 2017 – about the same probability of being killed by a falling coconut,
