An asteroid that passed by one-tenth of the distance from Earth to the moon is thought to have left a calling card yesterday: a meteorite that "caused an explosion and earth tremor, leaving a crater 12m (39ft) across and 5m deep near the city's airport."

Asteroid 2014 RC, which is 60 feet wide, "is expected to orbit near Earth again."
