An asteroid nine times larger than the QE2 is due to sail past the Earth later this month.
Luckily, the giant space rock will get no closer than 3.6 million miles, or 15 times the distance between the Earth and the moon.
Coincidentally, scientists have named the asteroid 1998 QE2. The name has nothing to do with the transatlantic Cunard liner - it follows a code used for newly-discovered asteroids by the US Minor Planet Centre in Cambridge, Massachusetts.
The asteroid is believed to be about 1.7 miles long, or nine times the length of the Queen Elizabeth 2 ship.
