I want to remind Steven Chesley and Paul Chodas* that the very small asteroid "2004FH" (estimated to be only about 100 feet across) was NOT the closest such asteroid to approach Earth in recent times. In August 10, 1972 one such small asteroid actually grazed the Earth's atmosphere before skipping back out into space. The trajectory of this asteroid took it over several mid-western U.S. states and Alberta where the fireball was witnessed by many and even filmed with a movie camera. The lowest point it came to the Earth was about 40 miles over Montana. 2004FH was estimated to have missed the Earth today by over 25,000 miles. Initial estimates of the size of the asteroid in the 1972 near- miss were up to about 20 feet across, later revised up to sizes over 250 feet if the asteroid had a composition similar to most stoney meteors. The latest published estimates placed its size somewhere between 10 and 50 feet across. It is interesting to note that at 122 feet in length, the Space Shuttle Columbia which broke up while entering Earth's atmosphere with a velocity of about 5 miles a second was bigger than either one of these two very small asteroids. Nick Balaskas *It was Paul Chodas who suggested that the mystery object or UFO found to be orbiting the Earth nearly two years ago was the third S-IVB stage (about 60 feet in length) of the Saturn V rocket that propelled the Apollo 12 astronauts to the Moon.
