Since larger space rocks are rare, it was surprising when my Catalina Sky Survey teammate Hannes Groller found a half mile diameter asteroid traveling through the constellation of Auriga.Fortunately on it’s current path 2024 JW1 can’t come closer than 53 lunar distances from us. Asteroid hunters will continue to track 2024 JW1 to make sure that it does not become a threat as it passes near Earth, Mars , and Jupiter.
