Small Asteroid Flew by Earth ...at a Distance of Approximately 3.2 million Miles
NASA Editor's note, June 5, 2020: Asteroid 2002 NN4 will safely pass by the Earth on June 6 at a distance of approximately 3.2 million miles (5.1 milliion kilometers), about 13 times further away from the Earth than the Moon is. There is no danger the asteroid will hit the Earth. As they orbit the Sun, Near-Earth Objects occasionally approach close to Earth.
