Mark this on your calendar: (via NASA) “On April 13, 2029, asteroid 2004 MN4 will fly past Earth only 18,600 miles (30,000 km) above the ground. For comparison, geosynchronous satellites orbit at 22,300 miles (36,000 km). ‘At closest approach, the asteroid will shine like a 3rd magnitude star, visible to the unaided eye from Africa, Europe and Asia–even through city lights,’ says Jon Giorgini of JPL. This is rare. ‘Close approaches by objects as large as 2004 MN4 are currently thought to occur at 1000-year intervals, on average.’”

A huge, massive asteroid passing closer to earth than the orbit of our satellites? Now that will be an impressive sight to see. 24 years from now. It should be worth the wait!
