The planet is about 600 light years away from Earth.
The asteroid 2005 YU55 safely flew past our planet slightly closer than the moon's orbit on Nov. 8. The last time a space rock this large came as close to Earth was in 1976, although astronomers did not know about the flyby at the time.
Astronomers have spotted an exotic planet that seems to be made of diamond racing around a tiny star in our galactic backyard.
A thin band of antimatter particles called antiprotons enveloping the Earth has been spotted for the first time.
A new theory suggests the Earth once had a small second moon that perished in a slow motion collision with its "big sister".
