Two small asteroids in unrelated orbits will pass within the moon's distance of the Earth on Wednesday, according to NASA.
It's an unusual event that shows the need for closer monitoring of near space for Earth-threatening encounters, a scientist with the program said.
The objects don't pose a threat to Earth, and they will not be visible to the naked eye, said Donald Yeomans, manager of NASA’s Near Earth Program, which tracks potentially hazardous asteroids and comets within 28 million miles of Earth.
The objects will visible from Earth as tiny specks of light with the help of moderate-sized amateur telescopes, he said.
