Scientists have said it will be possible to see the asteroid as it flies past the Earth tonight.
It will appear as a faint dot of light, moving at a "steady rate" between the stars.
It'll be thousands of times fainter than Jupiter and 250 times fainter than the stars of the Plough.
The trick will be to find the area in advance and wait for it to come through. You can use the star maps to find exactly the right part of the sky. If you hold your binoculars steady you will see this tiny point of light crawling across your field of view in about seven or eight minutes.
It's not easy, but you will have the thrill of knowing you are seeing a little object in space the size of an office block.
