Large space rock flies past earth
Space enthusiasts have been following a 300 metre-wide asteroid as it flew past Earth.
The space rock, named Apophis, has been put on a watch list by scientists, who say there is a very small chance it could collide with our planet in the future.
Its most recent fly-by was at a safe distance of about 14 million km.
But the asteroid was close enough for astronomers to study it and assess its future risk.
