Every year asteroid hunters discover about a hundred objects which are larger than 450 feet in diameter and come closer than 20 times the Moon's distance from us. We call these potentially hazardous asteroids. In 2015 my group the Catalina Sky Survey discovered 21 of them. It was thus exciting news to our team, when, recently, our newest team member Greg Leonard discovered three of them in rapid succession.
