With a diameter of only 7 metres (23 ft), scientists think that even if it had been on a direct collision course with Earth, it would have likely burned up in the atmosphere.[3] The space rock made its pass by Earth just fifteen hours after its discovery.[4]
The asteroid was first discovered by the Catalina Sky Survey at the University of Arizona. It was determined that the object would make a pass well within the orbit of the Moon, but would not strike Earth. The object passed so close to Earth that its orbit was modified by Earth's gravity.[4]

2009 VA — астероид, который прошёл на расстоянии около 14000 километров от Земли 6 ноября 2009 года, ближайший из трёх пролетевших в опасной близости рядом с Землёй. Его диаметр всего 7 метров. Специалисты считают, что даже если бы объект столкнулся с нашей планетой, то катастрофы бы не случилось; скорее всего, он бы просто сгорел в атмосфере. Астероид пролетел рядом с Землёй спустя 15 часов после его открытия.Другой контент может иметь иную лицензию.
