A huge asteroid up to five times as tall as Dublin's Spire will pass by Earth tonight, scientists have said.
Asteroid 2000 QW7 is between 300 and 600 metres long, according to NASA data, but it poses no danger.
The asteroid dwarfs famous landmarks, such as the 121m Spire, the 324m Eiffel Tower, and the 443m Empire State Building.
It will fly by around five million kilometres from Earth at 23,000/km/h, according to NASA's jet propulsion laboratory.
It is carefully tracked by space experts, and is expected to pass Earth at around 12.54am.
NASA has been aware of the asteroid since the year 2000 and is confident that it is not a threat.
As it continues to orbit the Sun, the asteroid is next expected to pass Earth in October 2038 and the space agency will continue to monitor it to determine whether it may pass closer to us in the future.
