Giant Asteroid 1998 OR2 passing Earth today
Visible through a telescope or watch online
ASTEROID 1998 OR2 will pass within four million miles of Earth today.
Although it is in no danger of colliding with our planet, the 1.5-mile-wide asteroid is classified as 'potentially hazardous'.
The Nasa-tracked rock's orbit is also expected to bring the object within a million miles of Earth in 2079.
Every year, the Earth is hit by about 6,100 meteors large enough to reach the ground - or about 17 every day. Most of them fall unnoticed, in uninhabited areas.
The fly-by comes just days after a much smaller asteroid, named 2020 HX3, flew past Earth at approximately 157,000 miles. The asteroid, measuring between 11 and 24 metres, skimmed the Earth on Friday, April 24, at a speed of 33,000 mph.
If you have a telescope you might be able to spot the giant rock flies by at 19,461 mph or you can watch live with Virtual Telescope from 6.30pm this evening
