An example list of near-Earth asteroids that passed more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2008.
- 2007 TU24 (~250 meters in diameter) passed 1.44 LD (554,000 km) from Earth on January 29, 2008.
- 2008 CE22 (~18 meters in diameter) passed between 0.9997 and 1.0023 LD (384,300 to 385,300 km) from Earth on February 6, 2008.
- (450894) 2008 BT18 (~650 meters in diameter) passed 5.9 LD (2.3 million km) from Earth on July 14, 2008.
- 2008 XK (~12 meters in diameter) may have passed as close as 0.23 LD (89,300 km) from Earth on December 5, 2008, but the nominal orbit suggests it passed nearer to 1.46 LD (560,500 km) from Earth instead.
