Caught on camera: Green fireball believed to be asteroid streaks across night sky

AUSTRALIA -- Night owls in a remote part of western Australia captured a stunning green fireball streaking across the night sky.

Astronomers believe it was "asteroid 2002 N-N-4," which was scheduled to pass Earth around 11:20 p.m. on Sunday.

It may look small, but that asteroid is estimated to be the size of six football fields.

Despite being clearly visible, NASA says the asteroid was more than 3 million miles away from our planet, 13 times further away than the moon, so there's no risk of it hitting the Earth.
